Find The Measure Of The Indicated Angle. Need Help Please.I Need Explanation

Answers

Answer 1

Answer:

BC =21.03540021

Step-by-step explanation:

We know the measure of angle B since the sum of the angles of a triangle add to 180

A + B+ C = 180

61+ B + 12 =180

B = 180 - 12 -61

B =107

Then we can use the law of sines to find BC

sin B           sin A

-------- = -------------

AC                BC

sin 107       sin 61

-------- = -------------

23                BC

Using cross products

BC  sin 107 = 23 sin 61

BC = 23 sin 61/ sin 107

BC =21.03540021

Answer 2

Answer:

20.12m

Step-by-step explanation:

180 - (12 + 61) = 107° = ∡B

[tex]\frac{23}{sin(107)} = \frac{a}{sin(61)}[/tex]                     *Cross Multiply*

[tex]a(sin(107)) = 23(sin(61))[/tex]      *Divide by sin(107)*

[tex]a = \frac{23(sin(61))}{sin(107)}[/tex]                         *Solve*

a = BC ≈ 20.12m

Answer: Translation to the left

Step-by-step explanation: Although it may appear at first that this graph represents a reflection across the y-axis, it actually represents a translation 7 units to the left. Every point in the object is moved in the same direction and the same distance to form the new image. If you count the number of units between A and A' or B and B' (and so on), you will find that each point has been shifted to the left 7 times.

The equation for this is ax^2+bx+ c. You get the answer by finding factors of A and C; multiply them to each other so example after you find a factors of A which would be D and E, and B which would be F and G; multiply D with F and E with G. After that see if the two answers you got add or subtract to get the same number as B. Find both of the factors like for this example the best factors to use for A well is 1•1 because thats the only factor possible and for C the best factor is 3•7 because since there both just multiply by one if you add them together you get 10. After you do all that this is the formula (Dx+/-G)(Ex+/-F) plug all the numbers in and then you get the answer (1x+7)(1x+3) more formal way:(x+7)(x+3)

Answers

It will cost $4 for 45 minutes and for 2 hours it will cost $8. If parked for 3 to 4 hours it will cost $16 for garage at BWI Airport.

What is the scope and domain?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the set of values it can take as input. After we enter an x value, the function outputs this set of values.

How are range and domain determined?

Graphs can be used to determine the domain and range of functions. The domain of a graph is made up of all the input values displayed on the x-axis because the term "domain" refers to the set of potential input values. The possible output values that make up the range are shown on y-axis.

The cosine of 55 1/2 degrees is approximately 0.566. What angle, in degrees, has a sine of approximately 0.566?

Answers

Given:

[tex]\cos (55\dfrac{1}{2})^\circ\approx 0.566[/tex]

To find:

The angle, in degrees, that has a sine of approximately 0.566.

Solution:

We know that,

[tex]\sin(90^\circ-x)=\cos x[/tex]

We have,

[tex]\cos (55\dfrac{1}{2})^\circ\approx 0.566[/tex]

Using the above trigonometric identity, it can be written as:

[tex]\sin (90-55\dfrac{1}{2})^\circ\approx 0.566[/tex]

[tex]\sin (90-\dfrac{110+1}{2})^\circ\approx 0.566[/tex]

[tex]\sin (90-\dfrac{111}{2})^\circ\approx 0.566[/tex]

Taking LCM, we get

[tex]\sin (\dfrac{180-111}{2})^\circ\approx 0.566[/tex]

[tex]\sin (\dfrac{69}{2})^\circ\approx 0.566[/tex]

How do I solve for the measures of the the interior angles of a polygon

Answers

Answer:

Step-by-step explanation:

To solve for the interior angles for a polygon,

subtract 2 from the number of sides then multiply with 180

i.e, (n-2)180

e.g, in the case of a triangle, (3-2)180 = 1*180 = 180

As for square, (4-2)180 = 2*180 = 360

A club plans to sell tote bags. The club members estimate they will sell 100 tote bags when the bags are priced at $11 each. For every price increase of $1, they estimate they will sell 10 fewer bags.
What is the estimated revenue, in dollars, when the bags are priced at $13 each?
(revenue = price × number sold)


1) 1,300

2) 1,100

3) 1,040

4) 880

Answers

The estimated revenue, in dollars, that the club will generate when the bags are priced at $13 each is 3) 1,040.

What is the revenue formula?

The revenue formula is the multiplication of the number of units sold and the price per unit.

To determine the total revenue, we must first ascertain the unit price and the quantity sold.

We know that market forces and the competitive environment determine the quantity sold or supplied.

The demand for tote bags at $11 = 100 units

Decrease in demand for every $1 price increase = 10 units

When the price is $13 each, the units to be sold = 80 (100 -10 x 2)

The total revenue at $13 each = $1,040 (80 x $13)

Total revenue at $12 each = $1,080 (90 x $12)

Total revenue at $11 each = $1,100 (100 x $11)

Thus, we can conclude that the club generates less revenue when it increases its price per tote bag from $11 to $13, justifying the interactions between supply, demand, and cost.

Hint: One way to solve this would be to find the unit rate for 1 cup of water, then

To find the unit rate, divide the 4 cups of water and the [tex]\frac{3}{4}[/tex] cups sugar by 4 to get a unite rate for 1 cut of water.

4 divided by 4 equals 1.

what is permutation?

The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order. like in the case of.

Step-by-step explanation:

if g varies inversely as the square root of h, and g = 9 when h = 121, find g when h = 81.

Answers

If g varies inversely as the square root of h, this means that the product of g and the square root of h is constant. We can represent this relationship using the equation g*sqrt(h) = k, where k is the constant value.

We are given that g = 9 when h = 121, so we can substitute these values into the equation to find the constant:

9sqrt(121) = k

Simplifying this expression gives us:

k = 911 = 99

Now that we know the value of the constant, we can use the equation to find g when h = 81:

g*sqrt(81) = 99

Solving for g gives us:

g = 99/sqrt(81) = 99/9 = 11

Therefore, when h = 81, g = 11.

  3.  B  (1, -7)

  4.  B  x < -4

Step-by-step explanation:

3. An ordered pair is a solution to a set of equations or inequalities when putting the x and y values into each expression makes the expression true.

Here, all of the y-values offered are less than 2, so we need to look at whether the given points satisfy the second inequality.

  A 0 -(-5) > 5   ⇒   5 > 5 . . . FALSE

  B 1 -(-7) > 5   ⇒   8 > 5 . . . True

  C -3 -(-4) > 5   ⇒   1 > 5 . . . FALSE

The point (1, -7) satisfies both inequalities, so is a solution of the system.

__

4. The boundary line of an inequality is solid when the "or equal to" case is included in the solution. The symbols used for that are ≤ or ≥. When the symbol is < or >, the "or equal to" case is not included, and the boundary line is dashed.

Here, you can answer the question based simply on the < symbol. There is only one inequality shown that will have a dashed boundary line: choice B.

__

On a usual graph, x-values increase to the right, and y-values increase in the up direction. This means lesser values of x or y are to the left or down. You can determine the side of a boundary line that is shaded by considering this fact.

All you really need to do is find a variable term with a positive coefficient and look at where it stands in relation to the inequality symbol. Here, we have ...

  x < (something)

This tells us the shading will be where x-values are less than (left of) those on the boundary line.

So, for x < -4, shading will be to the left of the dashed boundary line.
