ABC is rightangled triangle. AD is the bisector of angle BAC. Angle DAC=15 degrees. X=CD. Find X. I know the answer is 7.1 but do not know how to do the actual sum. Can you please help.

Answer 1

I do not know how too
if only angle given

Answer 2

There is something missing here.

1. where is the right-angle? (I assumed it was B)
2. some information about the length of sides has to be given.
(I assumed your answer of 7.1 for DC was correct and worked backwards. BC would have to be 13.25 )
