Answer 2

Step-by-step explanation:

In fig (iv)

3x-1=11 (opp. sides of llgm are equal)

=> 3x=11+1

=> x=12/3

=> x=4

and

2y-2=18 (opp. sides of llgm are equal)

=> 2y=18+2

=> y=20/2

=> y=10

in fig (v)

2y-1=17 (diagonals of llgm bisect each other)

=> 2y=17 +1

=> y=18/2

=> y=9

x+5=15 (diagonals of llgm bisect each other)

=> x=15-5

=> x=10
