Question

line jl and line km intersect at point h. find the three unknown angle measures in the figure.
first, find ( mangle khl ).
( mangle khl = 129^circ )
now, find ( mangle lhm ).
( mangle lhm=square^circ )

Explanation:

Step1: Use the property of vertical angles

Vertical angles are equal. $\angle LHM$ and the given $51^{\circ}$ angle are vertical angles.

Step2: Determine the measure of $\angle LHM$

Since vertical angles are congruent, $m\angle LHM = 51^{\circ}$

Answer:

$51$
