Question

find x and y if abcd is a parallelogram ​

Answer 1

$\huge\orange{\boxed{\boxed{\boxed{Answer}}}}$

x = 6

y = 9

Step-by-step explanation:

Since ABCD is a parallelogram

AD = CB

DC = AB

.

.

.

So,

a) 3x = 18

and

b) 3y-1 = 26

.

.

.

.

a) 3x = 18

x = 18/3

x = 6

b) 3y - 1 = 26

3y = 26 + 1

3y = 27

y = 27/3

y = 9

Answer 2

Step-by-step explanation:

$\bold{ \red{ \underline{We \: know \: that \: oppsite \: sides \: of \: the \: parallelogram \: are \: equal.}}} \\ \blue{So ,\: 26 = 3y - 1 \: and \: 18 = 3x.} \\ \red\implies \blue{27 = 3y \: and \: \frac{18}{3} = x. } \\ \red\implies \blue{ \frac{27}{3} = y,y = 9\: and \: x = 6.}$
