SOLUTION: AB intersects CD at E. If m angle BED = 5x+20 and m angle CEA = 7x+10, find m angle CEB

Question 31022: AB intersects CD at E. If m angle BED = 5x+20 and m angle CEA = 7x+10, find m angle CEB

I am not sure how to draw this problem on this site but angle BED will equal and CEA because they are opposite angles. A form of a rule from Geometry. First we need to find these angles
subtract 10 from both sides
subtract 5x from both sides
divide by 2

These angles equal 5 degrees. Knowing that the angle of a line is 180 degrees.

CEB = 175 degrees
