To extend that further, if the polygon has x sides, the sum, S, of the degree measures of these x interior sides is given by the formula S = (x - 2)(180). For example, a triangle has 3 angles which add up to 180 degrees. A square has 4 angles which add up to 360 degrees.

Answer:
-6
Step-by-step explanation:
Plug in x = 3 in the equation: 3(3 - 4) + 2(3) - (3)^2
Now simplify with order of operations:
3(3 - 4) = -3
2(3) = 6
-(3)^2 = -9
-3 + 6 - 9 = -6
