Question

The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees. The measure of the other 2 angles is equal. What is the measure of the other 2 angles?

Answer 1

67.5

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
