86 - 0
Step-by-step explanation: im not sure on the last two but i tried?
Triangles add to 180° and there is already 100° shown inside of the triangle (30° plus 70° = 100°). 180° -100° = 80°, which is x. X and y are vertical angles, so y is also 80°. The answer is B.
40+90=130
180-130=50
50+130=180
x=130
50+x=180
