What is the y-coordinate?
400

What are two ways I can find the measure of an exterior angle d, if a was 50 degrees and c was 55 degrees?
you could add a & c together because the exterior angle is the opposite interior angles added together. You could also add a & c and subtract that from 180 to find the third interior angle, then subtract that from 180 since b & d, form a straight line.

If two angles are alternate interior angles and angle 1 = 92 and angle 2 = 8x - 4. Find angle 2 and solve for x
angle 2 = 92 x = 12
