How to solve this question ​

Answer 1

BC = 3.6

Explanation:

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

`(BC)/(DE)` =
`(AC)/(AE)` , substitute values

`(BC)/(1.2)` =
`(4.5)/(1.5)` ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6
