Question

Angle 1 and 2 form a linear pair angle 1 and 3 are vertical angles m<1=57° What is m<3?

Answer 1

Angles 1 and 3, which are vertical angles, are congruent, and Angle 1 measures 57 degrees. Therefore, Angle 3 will also measure 57 degrees.

Step-by-step explanation:

Angle 1 and Angle 2 form a linear pair, which means they are adjacent angles that add up to 180 degrees. Angle 1 and Angle 3 are vertical angles, which means they are congruent. Since Angle 1 measures 57 degrees, Angle 3 will also measure 57 degrees.

Answer 2

The measure of <3 is 57 degrees

Step-by-step explanation:

Since 1 and 3 are vertical angles, that makes them equal so they are both 57
