Question

Find the unknown length y in the pair of similar triangles.

Answer 1

Explanation:

If 2 triangles are similar then the ratio of any 2 sides of one triangles will be equal to the ratio of any 2 sides of the another triangle.

So,

`(30)/(8) = (20)/(y)`

Cross-multiplying the denominators gives,

`30y = 160`

`= > y = (160)/(30) = (16)/(3)`
