Answer 1

AB = 2.625

Explanation:

BC is an angle bisector and divides the opposite sides into segments that are proportional to the other 2 sides , that is

`(CA)/(CD)` =
`(AB)/(BD)` , that ia

`(6)/(10)` =
`(AB)/(7-AB)` ( cross- multiply )

10 AB = 6(7 - AB) ← distribute

10 AB = 42 - 6 AB ( add 6 AB to both sides )

16 AB = 42 ( divide both sides by 16 )

AB = 2.625
