Answer:

Explanation:

If you simply need help, these all look like supplementary lines, which means, all angles added up form 180 degrees.

Take the first visible problem, 5x+60 = 180. That would make x = 24 degrees by solving an equation.

So basically set the sum of all given values to be 180 degrees and then solve.
