Question

The sum of the measure of two angles is 183.6 degrees. On angle has measure of 54 degrees. What is m, the measure in degrees of the second angle

Answer 1

Hey there, this is simple subtraction, we are going to subtract 183.6 from 54, 183.6-54=129.6, Therefore, the degree of the second angle is 129.6

Answer 2

Simple,

you have 2 angles...when added together they equal 183.6

The measure of one of those angles is 54°

What's the measure of the other angle?

183.6
-
54

=129.6

Thus, m=129.6, your answer.
