Question

The triangles are similar what is the value of x

Answer 1

Answer: 16

Explanation:

To get from 3 to 12, you multiply by 4

To get from 5 to 20, you multiply by 4

So you just multiply 4 by 4 to get x

Answer 2

x = 16

Explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

`(x)/(4)` =
`(20)/(5)` = 4 ( multiply both sides by 4 to clear the fraction )

x = 16
