Question

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

Answer 1

Step-by-step 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,

$\frac{30}{8} = \frac{20}{y}$

Cross-multiplying the denominators gives,

$30y = 160$

$= > y = \frac{160}{30} = \frac{16}{3}$
