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

Answer 1

x =
`(60)/(9)` and x =
`(45)/(8)`

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

`(x)/(15)` =
`(4)/(9)` ( cross- multiply )

9x = 60 ( divide both sides by 9 )

x =
`(60)/(9)`

and
`(x)/(5)` =
`(9)/(8)`

8x = 45 ( divide both sides by 8 )

x =
`(45)/(8)`

Answer 2

For the first one,

x = 10.

For the second one,

x = 12
