Question

What is the length of PR?
A. 7
B. 8
C. 6
D. 9​

Answer 1

C

Explanation:

The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is

`(AB)/(PQ)` =
`(AC)/(PR)` , substitute values

`(20)/(5)` =
`(24)/(PR)` ( cross- multiply )

20PR = 120 ( divide both sides by 20 )

PR = 6 → C
