Someone please help me on this question, and find angle C!

It's given that AE = BE  therefore triangle ABE is isoceles 

That means that angle A = angle B  therefore angles A + B = 114o  

The total of the internal angles of a triangle is 180o  therefore angle BEA = 66o  

 

Since angle BEA is 66o  then so is angle DEC because the two are vertical angles. 

So angle D + angle DEC = 31o + 66o = 97o   

The total of the internal angles of a triangle is 180o  therefore angle C = 83o
