Question

Find the unknown length y in the pair of similar triangles.30 ft8 ft18 ftyy=ft(Simplify your answer. Type an integer, fraction, or a mixed number.)

Answer 1

Given the figure of two similar triangles

So, the corresponding sides are proportions

So, we can write the following ratio:

`(y)/(8)=(18)/(30)`

Solve for y using the cross product:

`y=(8*18)/(30)=(144)/(30)=4(4)/(5)`

So, the answer will be y = 4 4/5
