Answer:
<3 = 60
Step-by-step explanation:
This assumes that nothing happens to line x. If angle one has a value, then < 3 will have the same value because the angles are vertically opposite.
Presumably, the five degrees is measured against line x. If line y moves clockwise, it means that <2 is decreasing and giving 5 of its degrees to <1.
Therefore <1 becomes 5 degrees larger.
<1 = 55 + 5
<1 = 60
That means that angle 3 = 60
