its a diagram
Hi Alondra. It will be hard for anyone to help you with this exact problem because we cannot see the diagram. Maybe if you described it, someone will be able to point you in the right direction.
A statement/reason table often starts with a restatment of what you are given and what you are trying to prove. You are given the diagram and "angle 3 = 66 degrees." What are you trying to prove?
Starting with what is given, you try to use the theorems and postulates of geometry to prove something, one step at a time. Sometimes it is a good idea to try to work the problem out backwards.
Do you see any triangles in the diagram? Perpindicular lines? Parallel lines? These things each come with a bunch of theorems that you can use.
Please describe the diagram the best you can and I would be happy to help you out.
