Question 389366: in the diagram of isosceles trapezoid abcd, ab = cd. the measure of angle b is 40 degrees more than the measure of angle a. find angles a and b Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! b = a + 40, and a+b = 180. Then a+a + 40 = 180, or 2a = 140, or a = 70 degrees. b = 70 + 40 = 110 degrees.
