Question

Angle DAC = Angle BAD What is the lenght of B-D Picture included

Answer 1

BD ≈ 2.7

Explanation:

AD is an angle bisector thus the following ratios are equal

`(AB)/(AC)` =
`(BD)/(CD)`, that is

`(8.1)/(5.9)` =
`(BD)/(2)` ( cross- multiply )

5.9BD = 16.2 ( divide both sides by 5.9 )

BD ≈ 2.7 ( to 1 dec. place )
