Question

part 2 - use the angle addition postulate to answer the following questions.

1. find ( mangle klm ) if ( mangle klb = 16^{circ} ) and ( mangle blm = 70^{circ} ).

Explanation:

Step1: Apply the angle addition postulate

The angle addition postulate states that if \(B\) is in the interior of \(\angle KLM\), then \(m\angle KLM=m\angle KLB + m\angle BLM\).

Step2: Substitute the given values

We are given that \(m\angle KLB = 16^{\circ}\) and \(m\angle BLM=70^{\circ}\). Substituting these values into the formula from Step 1, we get \(m\angle KLM=16^{\circ}+70^{\circ}\).

Step3: Calculate the sum

\(16^{\circ}+70^{\circ}=86^{\circ}\)

Answer:

\(86^{\circ}\)
