Answer:

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)
