My mother's boyfriend's son who is in 6th grade asked me a question about the math they are learning. I thought it wouldn't be too bad but I cannot for the life of me figure it out. A solution would be greatly appreciated.

I'm not sure what your question is. Are you asking why the third angle is 55 degrees or what are you asking? Please clarify and we'll try to help.
 
Since the angles e and f are labeled, and since there is not enough information to determine them, I'm guessing there is more to the question than calculating the ##55^\circ##. Please state the whole problem.
