Question

fig 3 find x and y it is parllelogm

Answer 1

Hello friends!!

Here is your answer :

We know that,

Opposite angles of a parallelogram is equal.

Angle DAB = Angle BCD

3x + 15 = 2x + 35

3x - 2x = 35 - 15

x = 20

DAB = 3x + 15

= 3(20) + 15

= 60 + 15

= 75

BCD = 2x +35

= 2(20) + 35

= 40 + 35

= 75

AB || CD

Sum of Co - interior angles is 180.

Angle BCD + Angle ABC = 180

75 + 2y + 5 = 180

80 + 2y = 180

2y = 180 - 80

2y = 100

y = 100 / 2 = 50


Therefore,

Value of x = 20

Value of y = 50


Hope it helps you..
