Math review question

This is the type of question that brings all of the angle relationships together.  I will make some notes below the photo to help you review a little bit.

I apologize for it not being done with a ruler.
- all straight lines (like the two parallel lines) add up to 180 degrees (there are three examples of supplementary angles going on in this drawing)
- I began to solve this question by filling in the unknown 70-degree angle in the triangle and seeing the ALTERNATE (Z shape) angle possibility 
- once I had this, I knew the angle to the right would be 110 degrees (180-70) and it is also confirmed because the CO-INTERIOR measures total 180 (70 + 110) which has a C shape
-  knowing two angles in the triangle (60, 70), I could do some subtraction to find the missing angle:
60 + 70 = 130; 180-130 = 50 degrees
-  just to be sure, the top 3 angles on line GA, when added, equal 180:  60 + 50 + 70 = 180

There are some other ways to explain this, but I do not want to put TOO much information.
