Question

Given NELR, solve for x.

Answer 1

The answer is 7, I don't know how I got it but it's 7

Answer 2

(D) 7

Explanation:

It is given that NELR is a parallelogram, then using the property of parallelogram, we have

`{\angle}N+{\angle}E=180{\circ}` (Sum of Corresponding angles of parallelogram is 180°)

`7x+33+11x+21=180^(\circ)`

⇒
`18x+54=180`

⇒
`18x=126`

⇒
`x=7`

Therefore, the value of x will be 7.

Hence, option (D) is correct.
