Question

10. The figures below are similar.

State the ratio of similarity and then use it
to find the value of x. (2 points)

Answer 1

x = 16.5

Explanation:

the ratio of similarity is the ratio of corresponding sides, that is

ratio =
`(18)/(12)` =
`(15)/(10)` = 1.5

Then

`(x)/(11)` = 1.5 ( multiply both sides by 11 to clear the fraction )

x = 16.5
