Question

find the value of x and y in each of the following parallelogram ​

Answer 1

Answer:

Given parallelogram has two diagonals

we know that diagonals are equal

so,

x-y=18 and x+y=16

x=18+y and y=16-x

sub y in x

x=18+(16-x)

x=18+16-x

x=34-x

2x=34

x=34/2

x=17

now sub x in y=16-x

y=16-17

y=-1

there fore x=17and y=-1
