What is the value of X?

Answers

Answer:

x = 60

Step-by-step explanation:

<DGC = 90 degrees Given

<AGB = <DGC Vertically opposite angles.

<AGB = 90 degrees. <AGB takes on the properties of <DGB

30 + x + 90 = 180 The three angles make up a line.

120 + x = 180 Combine like terms..

x = 180 - 120 Subtract 120 from both sides

x = 60

X=60 because angle G is 90° making the two angles D and E having to add up to 90 as well. D would =60 then because 90-30=60. Then angle X is vertical to that making the two angles congruent.

Answers

Answer:

shown below

Step-by-step explanation:

1. The pair of angles shown in your diagram are vertical angles. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. The pairs of vertical angles have the exact same measurement. Therefore, 5x and 100 must have the same degree measurement, or 100 degrees. Thus, 5x must equal 100, so 5x = 100, and x would be 20 degrees.

2. The diagram shows a right angle (90 degrees) formed by 3x degrees and 39 degrees. 3x and 39 are complementary, which means they add up to 90, not 180 (that's supplementary). Thus, 3x + 39 = 90, 3x = 51, and x = 17 degrees.

3. The diagram shows a 180-degree angle formed by 6x degrees and 2x + 8 degrees. This means that 6x + (2x+8) equals 180. 6x + 2x + 8 = 180 and 8x + 8 = 180, 8x = 172, and x = 21.5 degrees.

4. A angle's supplement is basically 180 - (angle measure), because you are finding the angle that when formed with the original angle creates a 180 degree angle. Thus, the supplement angle would be 180 - 47 which is 133 degrees.

5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.

Answer:

5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.

if a coin is flipped and a fair die is rolled 96 times, predict how many times you would flip a head and roll a 6

Answers

Answer:

Step-by-step explanation:

on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.

Now

On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)

But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2

In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together

So our required answer is

p(even number)× p(tails)= 1/2 × 1/2 = 1/4

The chalk circle around the pitcher's mound has a diameter of 16 ft. What is the area of the pitcher's circle?

Answers

Answer:

The area is approximately 201.06

Step-by-step explanation:

If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.

Answer: A≈201.06ft²

Step-by-step explanation:

How to Calculate Diameter?

Diameter = Circumference ÷ π (when the circumference is given)

Diameter = 2 × Radius (when the radius is given)

Diameter = 2√[Area/π] (when the area is given)

A suit originally costing $240 is on sale for 25% off the original price. Sales tax is 7.5%. What is the final cost of the suit? (Math)

Answers

$193.50

start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50

Find the value of the variable.

Answers

When you add all of these angles, the sum should be 180°. This helps us to figure out the value of the variable.

Now, you must create an equation.

3z+14+z+90=180

4z+14+90=180

4z+104=180

4z+104-104=180-104

4z=76

z=19

∴The value of the variable is 19.

To check:

3(19)+14+19+90

57+14+19+90

90+90

180

All of the angles together have a sum of 180 degrees, meaning that our value for the variable is indeed correct.

Hope this helps.

Answer:

z = 19

Step-by-step explanation:

These are complementary angles; both angles add up to 90°.

To solve this, we can combine like terms.

3z + (1)z + 14 = 90

3z + (1)z = 4z

**3z and z are the only pair of like terms.**

After combining like terms, we can proceed to solve this problem.

4z + 14 = 90.

Since there is an addition sign in front of 14, we do the opposite, subtraction.

First, subtract 14 from 90 and 14.

4z + 14 = 90

- 14 - 14

------------------

4z = 76

**ELIMINATE 14.**

Lastly, divide 76 from 4; this is because 4 is the coefficient.

4x = 76

76 ÷ 4 = 19

Therefore, z = 19.
