Can anyone help with these?
Don't understand how to do it

1) EA= 50 (because is a vertical angle with CB and vertical angles are congruent)

3) DEB = 210 ( to find AB subtract EA from 180, so 180-50 = 130. Then add together arcs DE, EA and AB to find the total measurement of DEB)

5) AB = 130 (I explain how to find it in question #3)

6) CDA = 180 ( To find CDA just add the measurements of CD, DE and EA together)

(sorry don't know the rest, hope this helps)
