Question

need proper method and answer​

Answer 1

Answer:

In a parallelogram ABCD

ANGLE A = ANGLE C

ANGLE B = ANGLE D [Opp. angles of parallelogram are equal]

Now it is given that ANGLE A = ANGLE B + 50

Now,

ANGLE A + ANGLE B + ANGLE C + ANGLE D = 360

[ANGLE B + 50] + ANGLE B +[ANGLE B + 50] + ANGLE B = 360

4 ANGLE B + 100 = 360

ANGLE B = 260/4

ANGLE B = 65 DEGREE

HENCE

ANGLE A = ANGLE B + 50 = 65 + 50 = 110 DEGREE

ANGLE B = 65 DEGREE

ANGLE C = ANGLE A = 110 DEGREE

ANGLE D = ANGLE B = 65 DEGREE
