Answer 1

diagram ?

Answer 2

can u give a diag? either attach a file or draw it

Answer 3

see opposite(above n below only) sides of parallelogram are parallel....so the angles 49 and the other marked become equal due to the property of alternate angles

Answer 4

the diagonal acts as a transversal of the 2 parallel sides

so it becomes 2y-1=49

Answer 6

no its wrong its 2y,25

Answer 7

shruti is correct.

Answer 8

how

Answer 9

2y-1=49
2y-1+1=49+1
2y=50
y=25

x+1=3
x=2
