Question

In the figure below, FJ and GI intersect at H to

form the angles shown.


What is the measure of FHI?
A. 45°
B. 90°
C. 135°
D. 180°​

Answer 1

C

Explanation:

∠ FHI and ∠ JHI form a straight angle and are supplementary, thus

3x + x = 180, that is

4x = 180 ( divide both sides by 4 )

x = 45

Thus

∠ FHI = 3x = 3 × 45 = 135° → C
