Question

What values of a would make the given quadrilateral a parallelogram.


PLZZZZZZzzZzZZ

HeLP mE GUYsssss.

Answer 1

As the diagonal of quadrilateral bisects each other; 5b-4=3b+6

2b=10

b=5

 

So by the same rule;3b-4=2a

15-4=2a

11=2a

a=11/2

Answer 2

SOLUTION:

As we know that, diagonals of ||gm bisect each other

∴ 5b - 4 = 3b + 6

=> 2b = 10

=> b = 5 units   ..........(1)

Also, 3b - 4 = 2a

=> 3 (5) - 4 = 2a.....[using (1)]

=> 11 = 2a

=> a = 5.5 units
