Question

1. find m∠klm if m∠klb = 26° and m∠blm = 60°.

Explanation:

Step1: Apply Angle Addition Postulate

The Angle Addition Postulate states that if a point \( B \) lies in the interior of \( \angle KLM \), then \( m\angle KLM = m\angle KLB + m\angle BLM \).
Given \( m\angle KLB = 26^\circ \) and \( m\angle BLM = 60^\circ \), we substitute these values into the formula.
\[
m\angle KLM = 26^\circ + 60^\circ
\]

Step2: Calculate the Sum

Add the two angle measures together.
\[
26^\circ + 60^\circ = 86^\circ
\]

Answer:

\( 86^\circ \)
