(could you do a step by step method i think it would help a lot)

Answer 1

27.6°

Explanation:

6.5²-6² = 6.25

✓6.25 =2.5

^^^ that was Pythagoras theorem

9+2.5 = 11.5

23-11.5 =11.5

6 = height =opposite

11.5 = base = adjacent

sohcahtoa

use Tan

Tan-¹(6/11.5)

gives the angle CDA = 27.5528...

27.6 (1d.p)
