Consider the image and read the proof. For every triangle, the sum of it's angles is $180º$. Moreover

We know that in the last figure $\angle b+\angle d = 180º=\angle a + \angle c + \angle b\Rightarrow \angle d = \angle c + \angle a$.

Apply this general results to your triangle and you will obtain the answer.
