I need help with this problem and problems like this. I know that to solve this problem I have to find which angles are the same and etc, but how do I know that. How can I see that two angles are the same or if their sum is a certain angle ?
For example like this problem:
In the following figure,AB ̅and ̅̅̅̅CD are parallel. Evaluate the angle x in terms of angles y and z.
How do I approach this problem ? Can you give me some tips for these types of problems ? I would really appreciate it.
