Answer:
63
Step-by-step explanation:
You have to subtract 180 and 117 which is 63.
Answer:
-10x^2 +9+8x^2-5x+7=-2x^2-5x+16
28 degrees. This is because the first angle is 12 degrees, the third is x degrees and the second is 5x. You know that in a triangle the angles add up to 180 degrees so 12 + 5x + x = 180. Then you get 6x =168 and x =28 degrees. (**x being the thrid angle**)
