Question

Practice using angle relationships.
Triangle H J K. Angle J is 96 degrees and angle H is 24 degrees. Point L extends from side H K.

What is the measure of AngleJKL?
60°
80°
110°
120°

Answer 1

Angle K = 180° − (96° + 24°) = 60°.
Since L is on the extension of HK beyond K, ∠JKL is the exterior angle supplementary to ∠HKJ, so ∠JKL = 180° − 60° = 120°.
