Answer: x = 12, ∠B = 45°

Step-by-step explanation:

Angle A and Angle B are alternate exterior angles meaning that they are equal

5x - 15 = 2x + 21

3x - 15 = 21

3x = 36

x = 12

B = 2(12) + 21

B = 24 + 21

B = 45

D=DVDs and G=Games solve for 2D+3G=15.50 and 3D+1G=12.05
kogti [31]

We have

1G = 12.05 - 3D;

Then,

2D + 3( 12.05 - 3D) = 15.50;

2D + 36.15 - 9D = 15.50;

- 7D = - 20.65;

D = 2.95;

Finally, G = 12.05 - 3 x 2.95;

G = 3.20;

The total number of yards is 360 yards

<h3>How to determine the number of yards?</h3>

The given parameters are:

Number of sheets = 8

Yard per sheet = 45 yards

The total number of yards is calculated as:

Total number of yards = Number of sheets  * Yard per sheet

Substitute the known values in the above equation

Total number of yards = 8 * 45 yards

Evaluate the product

Total number of yards = 360 yards

Hence, the total number of yards is 360 yards
