Homework Help: geometry

Prove that if angle DAC is 40 degrees and angle ACD is 35 degrees, then angle BDA is 70 degrees. Write a two column proof showing statements and reasons. My teacher said my answer was wrong because BCA cannot equal 40 degrees because lines DA and C are not parallel, but he did not give me the correct answer.
