Question

The pair of figures is similar. Find x. Round to the nearest tenth if necessary.

0.1 ft
4.5 ft
0.9 ft
4 ft

Answer 1

x = 4.5 ft

Explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

`(18)/(x)` =
`(8)/(2)` ( cross- multiply )

8x = 36 ( divide both sides by 8 )

x = 4.5
