Answer 1

Answer:

AB = 2.625

Step-by-step explanation:

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

$\frac{CA}{CD}$ = $\frac{AB}{BD}$ , that ia

$\frac{6}{10}$ = $\frac{AB}{7-AB}$ ( 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
