How have you tried to do it?
What do you mean by 'calculate both'?
These are cointerior angles on parallel lines so they are supplementary (add to 180 degrees) Does that help?
What do you need to do? Do you know now?
I want to help you understand and learn .. I do not think it is as likely to help you if I just give you the answers.
I am fairly certain that "calculate them both" means to find the measure of both unknown angles in the given diagram.
