Question

for the figure shown, find m∠1 and m∠2. m∠1=□° (the figure is not drawn to scale.)

Explanation:

Step1: Use exterior - angle property

The exterior - angle of a triangle is equal to the sum of the two non - adjacent interior angles. For the triangle with angles 32° and ∠1 and exterior angle 93°. So, 32°+∠1 = 93°.

Step2: Solve for ∠1

Subtract 32° from both sides of the equation: ∠1=93° - 32°.
