Question

If r= 3 cm, p = 2.4 cm, q = 1.8 cm, and m= 4.35 cm, what is the measure of n?

Answer 1

C

Explanation:

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

`(LM)/(PR)` =
`(LN)/(PQ)` ( substitute values )

`(n)/(1.8)` =
`(4.35)/(3)` ( cross- m ultiply )

3n = 7.83 ( divide both sides by 3 )

n = 2.61 cm
