Question

Three angles of a quadrilateral have the following measures: 60, 90, and 125. What is the measure of the missing angle. 75, 80, 85, and 90

Answer 1

i believe the answer is 85

Answer 2

The Answer is 85. You can figure this out by adding up the angles given (60, 90, 125) to get 275. Because all angles in a quadrilateral add up to 360, you subtract the 275 from the 360 to get your answer on 85. Hope this helps!
