In the roof design below, the lower support beam, A, is 16 feet. The vertical support beam, B, is 11 feet. The two beams meet at a right angle. What is the minimum length necessary for the angled support beam, C?
picture not drawn to scale
A.27 feet
B. 20 feet
C.40 feet
D25 feet

you should at least use a calculater

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
