Question

abcd is a parallelogram. find the value of X.​

Answer 1

x= 45

because,

opposite angle are equal in parallelogram

then

3x-50=x+40

3x-x=50+40

2x=90

therefore

x= 45

Answer 2

Answer:

option D is correct... As we know that sides and angles of parellogram are equal...

so, 3x - 50° = x + 40°

3x - x = 40° + 50°

2x = 90°

x = 90°/2

so, x = 45°

hope this will help u......
