Below Is A Rhombus With An Equilateral Triangle. Find The Measure Of A.

Answers

Answer 1

Answer:

  a = 80°

Step-by-step explanation:

In order to solve this figure, we need to find a useful relationship between the various angles. We can use the straight angle at the upper left vertex of the equilateral triangle.

__

The sum of angles there is ...

  a + 60° +(a/2) = 180°

  3/2a = 120° . . . . . . . . . . subtract 60°, collect terms

  a = 80° . . . . . . . . multiply by 2/3

_____

Additional comment

All triangles are isosceles, because they all have 2 (or more) sides the same length. That means the base angles are half the supplement of the a.pex angle. Of course, adjacent vertices of a rhombus have supplementary angles.

Find the median of the data.

24,74,61,29,38,27,68,54

Answers

Answer:

The median is 46

Step-by-step explanation:

To find the median, you must first order the numbers, from left to right, lowest to highest:

24, 27, 29, 38, 54, 61, 68, 74

Next, we have to find the number in the middle. We can do this by counting inwards one and crossing out each of the lowest and highest each time we get closer to the middle/center.

24, 27, 29, 38, 54, 61, 68, 74

   ,  27, 29, 38, 54, 61, 68,    

   ,      , 29, 38, 54, 61,      ,    

   ,      ,      , 38, 54,     ,      ,    

Now, if there is no exact middle, we would add them add divide by 2. If there was an exact middle, that would be the answer. But there isn't.

38 + 54 = 92

92 / 2 = 46

The perimeter of the polygon with the vertices L = (1, 4), P = (-1, -2),

N = (2, 0) and M = (4, 0) is approximately 17.93 units.

We have,

The polygon has the following sides:

LP, PN, NM, and ML.

The coordinates for each point are:

L = (1, 4)

P = (-1, -2)

N = (2, 0)

M = (4, 0)

The perimeter of the polygons.

= LP + PN + NM + ML

Using the distance formula for the distance between two points (a, b) and (c, d):

Distance = √((c - a)² + (d - b)²)

Let's calculate the distances between the points:

LP:

Distance(LP)

= √((-1 - 1)² + (-2 - 4)²)

= √((-2)² + (-6)²)

= √(4 + 36)

= √40

= 6.32

PN:

Distance(PN)

= √((2 - (-1))² + (0 - (-2))²)

= √((2 + 1)² + (0 + 2)²)

= √(3² + 2²)

= √(9 + 4)

= √13

≈ 3.61

NM:

Distance(NM)

= √((4 - 2)² + (0 - 0)²)

= √(2² + 0²)

= √4

= 2

ML:

Distance(ML)

= √((4 - 1)² + (0 - 4)²)

= √((4 - 1)² + (-4)²)

= √(3² + 16)

= √(9 + 16)

= √25

= 5

Now,

Perimeter = LP + PN + NM + ML

Perimeter ≈ 6.32 + 3.61 + 2 + 5 ≈ 16.93

Thus,

The perimeter of the polygon is approximately 17.93 units.

6-8x=7x-9x-36 i really need help

Answers

Answer:

Simplifying

6 + -8x = 7x + -9x + -36

Reorder the terms:

6 + -8x = -36 + 7x + -9x

Combine like terms: 7x + -9x = -2x

6 + -8x = -36 + -2x

Solving

6 + -8x = -36 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

6 + -8x + 2x = -36 + -2x + 2x

Combine like terms: -8x + 2x = -6x

6 + -6x = -36 + -2x + 2x

Combine like terms: -2x + 2x = 0

6 + -6x = -36 + 0

6 + -6x = -36

Add '-6' to each side of the equation.

6 + -6 + -6x = -36 + -6

Combine like terms: 6 + -6 = 0

0 + -6x = -36 + -6

-6x = -36 + -6

Combine like terms: -36 + -6 = -42

-6x = -42

Divide each side by '-6'.

Answers

Answer:

B

Step-by-step explanation:

assume a right angle between the house and the ground.

then the ladder is the hypotenuse and distance from ladder to house is d

using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{d}{15}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x = 15 ( divide both sides by 2 )

x = 7.5

distance from house to foot of ladder is 7.5 feet

How do you find the measure of angle A?

Answers

Answer:

m∠A = 18

Step-by-step explanation:

Formula:

the sum of the interior angles of a triangle is 180.

____________________

According to the formula :

    [tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]

⇔ x - 22  +  3x + 19  +  x - 17 = 180

⇔ 5x + (19 - 17 - 22) = 180

⇔ 5x + (2 - 22) = 180

⇔ 5x - 20 = 180

⇔ 5x = 180 + 20

⇔ 5x = 200

[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]

Conclusion:

m∠A = x - 22 = 40 - 22 = 18
