Answer:

The answer is C.

Step-by-step 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 :

[tex]JI = 5x + 4[/tex]

[tex]JK = 2x + 7[/tex]

[tex]JI = JK[/tex]

[tex]5x + 4 = 2x + 7[/tex]

[tex]5x - 2x = 7 - 4[/tex]

[tex]3x = 3[/tex]

[tex]x = 1[/tex]

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

[tex]JK = 2(1) + 7[/tex]

[tex]JK = 2 + 7[/tex]

[tex]JK = 9[/tex]
