The answer is D. 80°. Angle B is 60 because the angle is adjacent. That makes 60 the vertical angle for the second angle in the triangle with the 40. Since we know two of the angles, we add them together to get 100. 180-100 is 80°
Because the number of sides is 6 so the s go interior angles is 720. So if u want to get x u need to sum up the rest of the angles anf subtract from 720 giving an answer of 130
