Question

what is m∠1? m∠1=□°

Explanation:

Step1: Use the exterior angle theorem

The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Calculate \(m\angle1\)

Here, \(m\angle1=39^{\circ}+93^{\circ}\)

$$m\angle1 = 132^{\circ}$$

Answer:

\(132\)
