A square has two pairs of parrallel lines :) I hope it helps :)
180-130=50
180-96=84
angles in a triangle add up to 180
50+84=134
180-134=46
x=46 degrees

Step-by-step explanation:

Side length-80
So we know that for a Right Angle, both sides have to measure up to 90 degrees. If one side is 10, and both sides need to add up to 90, then we can take 10 away from 90. That would be 80. 80 + 10 = 90. So the missing side length is 80.
