Question

find the value of x and y in each of the following parallelogram 12,8,x+y,2x​

Answer 1

This figure is parallelogram and its opposite sides are equal.

So 8=2x

x=8/2 = 4

So value of x=4

Now 12= x+y

We know that value of x=4

So,12=4+y

y=12-4=8

Value of y=8

Answer 2

Answer:

8 = 2x (the opposite sides are equal)

or, x = 4

12 = x+y (the opposite sides are equal)

or, 4+y = 12 (x=4)

or, y = 12 - 4

or, y = 8
