What is m∠d ?
enter your answer in the box.

You have to use a series of postulates and theorems to answer the question. First, you have to find <CED. In order to do that, you need to use the Triangle Sum Theorem and Vertical Angles Theorem and find <AEB. You will get E as 121. Using this, you can find the angle missing in triangle CED. Using the Vertical Angles Theorem, <CED is 121°. Now, use the same Triangle sum theorem to find <CDE. You will get 32°. 

Angle D is 32°
