The center pole of a tent is 8 feet long, and a side of the tent is 12 feet long as shown in the diagram. If a right angle is formed where the center pole meets the ground, what is
the measure of angle A to the nearest degree?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
