Answer 1

The answer is C.

Explanation:

Given that ∠I and ∠K have the same angles so we can assume that this is an Isoceles Triangle where 2 sides are equal. So we can compare the expressions of JI and JK to get the value of x :

`JI = 5x + 4`

`JK = 2x + 7`

`JI = JK`

`5x + 4 = 2x + 7`

`5x - 2x = 7 - 4`

`3x = 3`

`x = 1`

Next, we have to substitute the x value into the expression of JK :

`JK = 2(1) + 7`

`JK = 2 + 7`

`JK = 9`

(Correct me if I am wrong)
