Question

solve X and Y given in the above picture ​

Answer 1

Answer:

2y+ 13 = 5y + 4

5y-2y = 4-13

3y = -11

y = -11/3

X + 8 = 16-X

X + X = 16 - 8

2 X = 8

X = 4

$x = 4 \\ y = \frac{ - 11}{3}$

Answer 2

$In \: ABCD \: parallelogram, AC \: and \: BD$

$are \: diagonals \: intersecting \: at \: 'O' .$

/* We know that , */

$\pink{ (Diagonals \: bisects \: each \: other }$

$\pink{ in \: a \: parallelogram )}$

$i ) OA = OC$

$\implies x + 8 = 16 - x$

$\implies x + x = 16 - 8$

$\implies 2x = 8$

$\implies x = \frac{8}{2}$

$\green { \therefore x = 4}$

$ii) OB = OD$

$\implies 5y + 4 = 2y + 13$

$\implies 5y - 2y = 13 - 4$

$\implies 3y = 9$

$\implies y = \frac{9}{3}$

$\green { \therefore y = 3}$
