Question

first, find m∠khl.
m∠khl = \\(\square\\)°

Explanation:

Step1: Identify angle relationship

∠KHL and the 51° angle are supplementary (form a linear pair), so their sum is 180°.

Step2: Calculate m∠KHL

Use the formula \( m\angle KHL = 180^\circ - 51^\circ \).
\( 180 - 51 = 129 \)

Answer:

129
