Question

A mechanic is constructing the metal structure shown.

Both F) and IK measure 4 m and are perpendicular to GH. The measure of ZKIH = 40° and GJ HK.
What is the measure of ZFGJ?
A. 20°
O B. 40°
O C. 50
O D. 90°

Answer 1

C) 50°

Explanation:

Δ FJG ≅ Δ IKH

∡J = 90

∡I and ∡F = 40

therefore, ∡G = 180 - (90+40) = 50°
