How do I solve this?

Neporo4naja [7]

Answer:

v = 22

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BI}{MO}$ = $\frac{BG}{MP}$ , substitute values

$\frac{v}{33}$ = $\frac{64}{96}$ ( cross- multiply )

96v = 2112 ( divide both sides by 96 )

v = 22
