Question

LMNO is a parallelogram if NM=x+17, and OL= 3x+5, find the value of x, and then find NM and OL

Answer 1

x = 6 ; OL = 23 ; LM = 23

Explanation:

In parallelogram's opposite side's are equal.

OL = LM

3x +5 = x + 17

3x - x = 17- 5

2x = 12

x = 12/2

x = 6

OL = 3*6 + 5 = 18 + 5 = 23

LM = x + 17 = 6+ 17 =23
