WebThe angles in the triangle add up to 180 degrees. So a + b + y = 180. The angles on a straight line add up to 180 degrees. So x + y = 180. Therefore y = 180 - x. Putting this into the first equation gives us: a + b + 180 - x = 180. Therefore a + b = x after rearranging. This is what we wanted to prove.
