Hi Yo! I will give you some hints instead of the full solution.
1) Part c already asks you to find BC. With that you can find CD.
2) Cos ADC = adjacent over hyp
= CD/AD
Alternatively
Use Pythagoras theorem to find CD
Once you have CD you can find cos ADC.
If you have any questions, feel free to contact me
