Question

What is the value of h in the diagram below? If necessary, round your answer

to the nearest tenth of a unit.

A. 8.1
B. 9.1
C. 23
D. 3

Answer 1

A - 8.1

Explanation:

This is an example of similar shapes.

The length of MO is 18, and PO is 5.

So length of MP is 13. (18 - 5)

We need to separate this large triangle into 2 triangles:

• Triangle NMP

• Triangle NPO

In problems including similar shapes, our unknown needs to be on top of the fraction in an equation.

NP (h) /

`{(NP)/(MP)` =
`(PO)/(NP)`

`(h)/(13)` =
`(5)/(h)`

Cross multiply

h² = 65

h = √65

h = 8.06

h = 8.1 (rounded)
