Question

ABCD is a trapezium in which AB parallel DC if angle A=angle B=40degree what are the measures of the other two angles

Answer 1

Here the basic angles are equal so, quadrilateral abcd is is isosceles trapezium angle a= angle b
angle sum property of quadrilateral angle a+angleb+ angle c+ angle d = 360
X+X+80=360
2x = 280
X=140
