Question

Find MN. Need help with this. Thanks.

Answer 1

Answer:

D

Step-by-step explanation:

ΔMLN and ΔQPN are similar triangles thus the ratios of corresponding sides are equal.

$\frac{MN}{QN}$ = $\frac{ML}{QP}$, that is

$\frac{MN}{9}$ = $\frac{6}{8}$ ( cross- multiply )

8MN = 54 ( divide both sides by 8 )

MN = $\frac{54}{8}$ = 6 $\frac{3}{4}$ → D
