Answer:
angle 2 = 90° {corresponding angles}
angle 7 + angle 5 = 180° {linear pair}
or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}
so, angle 7 = 80°
Remember that the angles in a triangle add to 180 degrees. So, to solve, you add the two angles you have and subtract that difference from 180.
