Question

A right triangle, JKL, is given with KJL = 30° and JKL = 90°. KM is drawn such that L, K, and M are collinear. points J and M are joined by JM with JM = JL. Find JML and explain your answer.

A- 30°
B-90°
C-180°
D-60°

Answer 1

I tried but soory I can't understand

Answer 2

D-60°

Explanation:

K,L,M is collinear and JM=JL

M can only be extend to the left of K, otherwise it will overlap with L

JM = JL ΔJML is isosceles triangle ∠JML ≅ ∠JLM

∠JLM = 90 - ∠KJL = 90 - 30 = 60

∠JML = 60°
