I need help with this question. Can you please help me. I’ll give you 18 points if it’s correct

Answer:

34.4

Step-by-step explanation:

Using Triangle Sum Theory, you see that the triangles are similar. They have the same angle measurements. That means their corresponding sides are proportional.

$\frac{MN}{NO}$ = $\frac{PQ}{QR}$

$\frac{14}{11}$ = $\frac{PQ}{27}$

Cross multiply

14(27) = 11(PQ)

378 = 11(PQ)

$\frac{378}{11}$ = PQ

PQ = 34.4
