Question

Need help figuring out what X is?

Answer 1

x = 3.5

Explanation:

Since CD is the angle bisector of ∠ACB then the following ratios are equal

`(AC)/(BC)` =
`(AD)/(DB)`

substitute the given values into the equation

`(5)/(6)` =
`(x)/(4.2)` ( cross- multiply )

6x = 21 ( divide both sides by 6 )

x = 3.5
