Question

The sum of the angle measures of any triangle is

180
degrees. Suppose that one angle in a triangle has a degree measure of
−10x2
and another has a degree measure of
+6x5
. Write an expression for the degree measure of the third angle in the triangle.

Answer 1

Equation: x=180-[(-10×2)+(6x+5)]
Expression: 180-[(-10×2)+(6x+5)]

Answer 2

180 - (-10*2) + (6*5)
