Question

plz tell this with explanation​

Answer 1

Step-by-step explanation:

for a parallelogram

Length of opposite side always be equal

so

(a)

$y - 1 = 4 \\ y \:= 4 + 1 \\ y = 5$

$2x = 6 \\ x = \frac{6}{2} \\ x = 3$

(2)

$5y - 2 = 8 \\ 5y = 8 + 2 \\ 5y = 10 \\ y = \frac{10}{5} \\ y = 2$

$3 - x = 2 \\ 3 - 2 = x \\ 1 = x \\ x = 1$

(c)

here if it is parallelogram

then

OM=OQ

OP=ON

$6 = y + 3 \\ y = 6 - 3 \\ y = 3$

$2x + y = 4 \\ 2x + 3 = 4 \\ 2x = 4 - 3 \\ 2x = 1 \\ x = \frac{1}{2}$
