Answer 1

Answer:

x=9,y=8. (ii) x=12,y=5

Answer 2

Step-by-step explanation:

1)

$3x = 18 \\ 3y - 1 = 26 \\ because \: opposite \: sides \: of \: ||gm \: are \: equal \\ 3x = 18 \\ x = \frac{18}{3} = 6 \\ \\ 3y - 1 = 26 \\ 3y = 27 \\ y = \frac{27}{3} = 9$

hence, x is 6 and y is 9.

2)

In parallelogram diagonals bisect each other, that means if the point where diagonals are intersecting is O. then, SO = OU

20 = y+7

$20 = y + 7 \\ 20 - 7 = y \\ 13 = y$

as y = 13,

$16 = x + y \\ 16 = x + 13 \\ 16 - 13 = x \\ 3 = x$

hence, x = 3 and y = 13
