Answer:
67.5
Step-by-step explanation:
If all triangles equal 180 degrees, and one angle is 45 degrees, you get the equation 180 = 45 + x + x which is the same as 180 = 45 + 2x, and instead of that equation, you can use 180 - 45 = 2x. That gives you 135 = 2x, and now divide both sides by 2 and you get 67.5 = x
