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

Step-by-step 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
