Question

Can anyone help?

Answer 1

If `AB=6`, then `CD=6`.
────────────
You know that `BD=10`
────────────
Use `a²+b²=c²` to find CD
────────────
After you find CD, you will know that AC=12 (As AB+BC = 6+6 = 12)
────────────\
After you know AC, and CD use `a²+b²=c²` again to find AD.

Answer 2

These are the steps to your problem.

Answer 3

is CD 136?

Answer 4

Answer 5

CD can't possibly be 36.

Answer 6

whoops my bad didn't mean that!

Answer 7

BC is 6.
BD is 10.

6² + `CD`² = 10²
36+ `CD`² = 100
`CD`² = 64
`CD` = 8

Answer 8

okay but what step is next?

Answer 9

@SolomonZelman

Answer 10

CD=10
AC=12
AD=??

`CD`² + `AC`² = `AD`²
`10`² + `12`² = `AD`²
100 + 144 = `AD`²
244 = `AD`²
`AD` = 2√61 ≈ 15.62

Answer 11

Its not one of the choices tho? @SolomonZelman
