Question

1. find m∠klu, if m∠ulm = 20° and m∠klm = 110°.

Explanation:

Step1: Identify angle - relationship

We know that $\angle KLM=\angle KLU+\angle ULM$.

Step2: Solve for $\angle KLU$

By re - arranging the formula, we get $\angle KLU=\angle KLM - \angle ULM$.
Substitute $m\angle KLM = 110^{\circ}$ and $m\angle ULM=20^{\circ}$ into the formula: $m\angle KLU=110^{\circ}- 20^{\circ}$.
$m\angle KLU = 90^{\circ}$

Answer:

$90^{\circ}$
