Question

what is m∠1? m∠1 =

Explanation:

Step1: Recall exterior - angle property

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

Step2: Identify non - adjacent interior angles

The non - adjacent interior angles to ∠1 are 33° and 117°.

Step3: Calculate m∠1

m∠1=33° + 117° = 150°

Answer:

150
