Question

The measure of angle x in the picture.

Answer 1

130 degrees. A triangle is worth 180 degrees so first you have to find the third angle of the triangle which is 50 degrees (180-75-55=50) then the 50 degrees and the x are supplementary angles, meaning they add up to 180. So you do 180-50=130

Answer 2

180-75-55=50
Because co exterior angles are equal to interior angles
