Two angles 1< and 2< in a diagram are supplementary if m<1=77 what equation can you write to solve for m<2? Let m<2=x

The equation can be written as follows:

m<1 + m<2 = 180

Given that m<1 = 77:

77 + m<2 = 180

Therefore, the equation to solve for m<2 is:

m<2 = 180 - 77

Simplifying,

m<2 = 103
