Answer both please man. Or sorry you'll get a 1 star rating. THanks for answering guys!

Answer 1

x = $\frac{60}{9}$ and x = $\frac{45}{8}$

Since in both cases the figures are similar then the ratios of corresponding sides are equal

$\frac{x}{15}$ = $\frac{4}{9}$ ( cross- multiply )

9x = 60 ( divide both sides by 9 )

x = $\frac{60}{9}$

and $\frac{x}{5}$ = $\frac{9}{8}$

8x = 45 ( divide both sides by 8 )

x = $\frac{45}{8}$

Answer 2

For the first one,

x = 10.

For the second one,

x = 12
