Question

D. Evaluate x and y in the following figure
17 cm
A А
B
(2y + 7) cm
O
19 cm
D
c
(3x + 2) cm​

Answer 1

Step-by-step explanation:

Correct option is

A

x=3 and y=13

RUNS is a parallelogram and thus its diagonals bisect each other.

∴ x+y=16 ---- ( 1 )

and 7+y=20

∴ y=20−7

∴ y=13cm

Substituting y=13 in equation ( 1 ) we get,

⇒ x+13=16

⇒ x=16−13

∴ x=3cm

∴ x=3cm and y=13cm
