Answer:

Option C

Step-by-step explanation:

From the given figure, it is clear that the two triangles are similar to each other with QR = KL

As we know

QR = 3x+4 and KL = 15, we can derive the value of X

3X+4 = 15

X = 11/3

Jl = 2X + 10 = 2*11/3 +10 = 22 +30/3 = 52/3 = 18

hence, option C is correct
