Two angles, 1 and 2, in a diagram are supplementary. If m1 = 77, what equation can you write to solve for m2? let m2 = x

1 answer

The sum of two supplementary angles is 180 degrees.

Therefore, the equation would be:

m1 + m2 = 180

Given that m1 = 77 and m2 = x, the equation becomes:

77 + x = 180

Solving for x:

x = 180 - 77
x = 103

Therefore, the measure of angle 2, m2, is 103 degrees.
