Explanation:

angle 2 is supplementary to angle 1 (together they have 180°).

so,

180 = angle 1 + angle 2 = 143 + angle 2

angle 2 = 37°

and when 2 lines intercept, the angles on both sides of either line are the same (just left-right mirrored, because they are upside-down views from each other).

so,

angle 3 = angle 1 = 143°

angle 4 = angle 2 = 37°
