Question

the measure of two angles of a quadrilateral are 120 degree and 50 degree and the other two angles are equal find the measure of each of the angles

Answer 1

120°, 50°, 95°, 95°

The sum of the 4 angles in a quadrilateral is 360°

the 2 equal angles = 360° - (120 + 50)° = 190°

each of the equal angles = $\frac{190}{2}$ = 95°
