Two angles,<1 and <2, in a diagram are supplementary. If m<1 = 77°what

Question

equation can you write to solve for m<2 Let m<2 = x°
A x = 90 -77
B x = 77
C x+ 77 = 180
D x + 77 = 90

Answer 1

The correct equation to solve for m<2 would be:

C) x + 77 = 180

Since two angles are supplementary, their sum is equal to 180 degrees.
