Question

Find the unknown length, x, for the similar triangles below.

Answer 1

x = 26.4 m

Explanation:

Given the triangles are similar , then the ratios of corresponding sides are in proportion.

the corresponding sides are

x and 11 , 15.6 and 6.5 , 33.6 and 14

Then

`(x)/(11)` =
`(15.6)/(6.5)` ( cross- multiply )

6.5x = 11 × 15.6 = 171.6 ( divide both sides by 6.5 )

x = 26.4 m
