Answer:
x = 70
Step-by-step explanation:
Because these are two parallel lines, they both have the same angle measures. So, the angle measures of the top intersection are: 45, 45, 135, 135.
We know this because the angles adjacent to the 45 degree angle must be 135 degrees. Because they are supplementary angles (add up to 180).
That means that the angle that contains x must also be 135 degrees, and
2 x 70 - 5 = 135!
