Question

The sum of two opposite angle of a quadrilateral is 280 the other two angles are equal find the measurement of the equal angles

Answer 1

40.w.k.t sum of all angles in quadrilateral are 360. then 280+2y=360=y=40

Answer 2

ĂŃŚŴĔŔ

Let the measure of the other 2 angles be x

So, x + x + 280 = 360° (angle sum property)

2x + 280 = 360°

2x = 360° - 280°

2x = 80

x = 80/2 = 40

therefore, x = 40°
