Question

What is the measure of Angle c?

Answer 1

90 degrees

Explanation:

C and the 90 degree angle are vertical angles, which means they are congruent.

Answer 2

90

Explanation:

The sum of the angles is 360 degrees

42+48 + 90+ 42+48+c = 360

Combine like terms

270+c = 90

c = 360-270

C = 90
