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 = \\(\square^\circ\\)

Explanation:

Step1: Identify supplementary angle pair

$\angle KHL$ and the $51^\circ$ angle form a linear pair (supplementary, sum to $180^\circ$).

Step2: Calculate $m\angle KHL$

$m\angle KHL = 180^\circ - 51^\circ$

Answer:

$129^\circ$
