Question

Can someone help me please!!?

Answer 1

AB = 21

Explanation:

the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is

`(AE)/(ED)` =
`(AB)/(BC)` ( substitute values )

`(14)/(12)` =
`(AB)/(18)` ( cross- multiply )

12 AB = 14 × 18 = 252 ( divide both sides by 12 )

AB = 21
