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 relationship

Line \( JL \) and line \( KM \) intersect at \( H \), so \( \angle KHJ = 51^\circ \) and \( \angle KHL \) are supplementary (form a linear pair, sum to \( 180^\circ \)).

Step2: Calculate \( m\angle KHL \)

Use the linear pair property: \( m\angle KHL = 180^\circ - 51^\circ = 129^\circ \).

Answer:

\( 129^\circ \)
