Answer:

7A. x = 6

7B. m∠ABC = 135°

Explanation:

7A. I forget what the rule is called specifically, but the opposite angle is always congruent. So, you simply end up solving for x when you set the equation to equal 45.

7B. Use the supplementary rule, which basically states that two angles on a flat plane, when adjacent, equal 180°. So, 180 - 45 = 135.

God, my terminology is awful, but that's besides the point.
