Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
Answer:
10560 square feet
Step-by-step explanation:
If 2 sides are 48 feet, then we are left with
feet for the remaining side pieces.
feet.
So our dimensions must be 48 x 62.
This gives us an area of
