I would say 46 :)

OpenStudy (anonymous):

how'd you get get that?

OpenStudy (anonymous):

well measure CDA is 44 and measure CBA is only a little bit bigger.. that's how I got it.. and everytime I do questions like these, I get them correct.. so yea :) plus I did a question like that in my state test practice and got it right :)

hope I helped ! :) @ vivianrush

I forget what it's called, but there's a theorem that tells you that angles ACB and ADB are right angles. If CDA is 44, then CDB is 90-44 = 46. DPB is 90 degrees, so DBA can be found from (and note DBA = CBA \[\Large DBA + 90+46= 180\]
