Question

In AGHI, the measure of ZI=90°, the measure of ZG=5°, and IG = 57 feet. Find the

length of GH to the nearest tenth of a foot.

Answer 1

9514 1404 393

Answer:

57.2 ft

Explanation:

The relevant trig relation is ...

Cos = Adjacent/Hypotenuse

cos(G) = IG/GH

GH = IG/cos(G) = (57 ft)/cos(5°)

GH ≈ 57.2 ft
