Question

Please help, math, triangles.

Answer 1

MN = 4.5 ft

Explanation:

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

`(MN)/(JK)` =
`(LN)/(LK)` , substitute values

`(MN)/(12)` =
`(6)/(16)` ( cross- multiply )

16MN = 72 ( divide both sides by 16 )

MN = 4.5 ft
