Find the measure of each angle described.

Question

Find the measure of each angle described.

If m<C=131, then what is the measure of the supplement of <C?

Answer 1

You ought to have learned, from the definition of supplementary angles, that the measure of an angle's supplement is computed by subtracting that measure from 180 degrees.

Answer 2

Let x = the measure of the supplement to <C

m<C + x = 180

131 + x = 180

x = 49º
