If Úc ≅ Úd, mÚc = 5x  7, and mÚd = 3x + 25, how many degrees are in Úc?

Please first explain your ≅ and Ú symbols. On my computer screen, they do not make sense.

looks to me that you would be just solving
5x7 = 3x + 25
and then putting that value of x back into 5x7 
I updated my Firefox for Mac and now am getting another unrecognizable symbol, , in your question.
