The sum of the angle measures of any triangle is
180
degrees. Suppose that one angle in a triangle has a degree measure of
7x+3
and another has a degree measure of
3x-6
. Write an expression for the degree measure of the third angle in the triangle.

7x+3+3x-6+?=180



?=180-10x

The sum of the angle measures of any triangle is 180 degrees. It should be that a + b + c = 180. For this problem, we are given the two angles which we assume to be a and b so,

180 = 7x+3 + 3x-6 + c
c = 180 - (7x+3 + 3x-6) 
c = 180 - (10x - 3)
c = 177 - 10x

Hope this answers the question. Have a nice day.
