Question

line jl and line km intersect at point h. find the three unknown angle measures in the figure. first, find m∠khl. m∠khl =

Explanation:

Step1: Identify angle - type relationship

$\angle KHL$ and the $51^{\circ}$ angle are supplementary.

Step2: Use supplementary - angle formula

$m\angle KHL=180 - 51$

Step3: Calculate the angle measure

$m\angle KHL = 129^{\circ}$

Answer:

$129$
