Question

ABCD is a parallelogram in which angle a Is equal to 110 degree. Find the measure of each of the angles B,C and D

Answer 1

C=110 (opposite angles of a parallelogram is equal)
B=70 (co. interior is 180)
D=70(opposite angles of a parallelogram is equal)

Answer 2

let
angle A=110
in parellogram OPPOSITE ANGLES are equal
IE ANGLE A =ANGLE C=110
A+D=180
110+D=180
D=70
AngleD=angleB=70
