Radius of semi circles is 10 ft.
Area of semi circle is half the area of a normal circle.
Area of two semicircles: 1/2 * pi r^2 + 1/2 * pi r^2 = pi * r^2
So area of two semicircles with radius 10 ft = pi * 10^2 = 100 pi
Area of qtr circle: is quarter the area of a normal circle
Area of a quarter circle: 1/4 * pi r ^2
quarter circle has radius of 20 ft so area of it is 1/4 * pi * 20^2 = 100 pi
Total area = area of two semi + area of quarter
= 100pi + 100pi
= 200pi
≈ 628 ft²

The formula for finding the sum of the interior angles<span> of a </span>polygon<span> is the same, whether the </span>polygon<span> is regular or irregular. So you would use the </span>formula<span> (n-2) x 180, where n is the number of sides in the</span>polygon<span>. If you draw a diagonal in the square, that forms two triangles.</span>

Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°
