Question

Triangles ABC and ACD are similar.
AB=5cm and AC=6cm

Calculate the length of AD ​

Answer 1

Answer:
7.2cm
Explanation:

Answer 2

AD = 7.2 cm

Explanation:

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

`(AB)/(AC)` =
`(AC)/(AD)`, substituting values

`(5)/(6)` =
`(6)/(AD)` (cross- multiply )

5AD = 36 ( divide both sides by 5 )

AD = 7.2
