How to solve this question ​

Answer 1

Answer:

BC = 3.6

Step-by-step explanation:

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

$\frac{BC}{DE}$ = $\frac{AC}{AE}$ , substitute values

$\frac{BC}{1.2}$ = $\frac{4.5}{1.5}$ ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6
