Answer 1

Y= 64°
180°-116°= 64°
x= 99°
360°-(125°+72°+64°)= 99°

sum of interior angles of polygon S=(n-2)×180°
(4-2)×180°= 360°

Answer 2

First off, y is equal to 180 degrees minus 116 degrees because of the definition of supplementary angles. Thus, y would be equal to 64 degrees. Next you would have to find y. The sum of all angles in any quadrilateral is 360 degrees. All you would have to do is subtract (64 degreesplis 72 degrees plus 125 degrees) from 360 degrees. This would give you a final answer of x = 99 degrees.
