how do i do this?

hey I don't have calculator with me but i would suggest making AD whatever length you like i.e. 1, then find DB and DC

to find DB: tan50 = 1/DB
                 DB = 1/tan50

to find DC: tan33 = 1/DC
                 DC = 1/tan33

with these results then do DC/DB and this should give you the ratio :)
