Question

IfMNO~ QRS, find x. Round to the nearest tenth.
MN = 10
NO=x
QR=5
RS 7

Answer 1

x = 14

Explanation:

given Δ MNO and Δ QRS are similar then the ratios of corresponding sides are in proportion , that is

`(NO)/(RS)` =
`(MN)/(QR)` ( substitute values )

`(x)/(7)` =
`(10)/(5)` = 2 ( multiply both sides by 7 to clear the fraction )

x = 7 × 2 = 14
