Question

Help me on this question plzzzzz

Answer 1

see explanation

Explanation:

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

`(AC)/(XZ)` =
`(AB)/(XY)` , substitute values

`(9)/(XZ)` =
`(4)/(16)` ( cross- multiply )

4XZ = 144 ( divide both sides by 4 )

XZ = 36 cm

-------------------------------------------------------

Also

`(BC)/(ZY)` =
`(AB)/(XY)` , substitute values

`(BC)/(48)` =
`(4)/(16)` ( cross- multiply )

16BC = 192 ( divide both sides by 16 )

BC = 12 cm
