Hello!
So for the answer to the first problem, you would need to work it out.
Since two interior angles equal 180 degrees, your equation would be:
5x + 9x+26 = 180
From there, you would combine like terms, subtract, then divide.
14x + 26 = 180
14x = 154
x = 11.
Therefore, the answer is the second bubble, 11.

For the second question, the answer is the second bubble as well, because alternate interior means opposite sides, and not directly up and down (if that made sense). It is j || k and not g || h, because the two angles are on line h only, and in order for that to be g || h, one of the angles had to be on line g as well. Which makes j || k, qualified.
Hope that helped!
