Question

1. what is the measure of angle hjl in the picture below? 140° 45° 50° 40°

Explanation:

Step1: Identify angle - relationship

We know that $\angle HJK = 90^{\circ}$ and $\angle LJK=40^{\circ}$.

Step2: Calculate $\angle HJL$

$\angle HJL=\angle HJK-\angle LJK$.
So, $\angle HJL = 90^{\circ}- 40^{\circ}=50^{\circ}$.

Answer:

$50^{\circ}$
