Answer 1

Explanation:

the sum of all angles in a triangle is always 180°.

the sum of all angles around a single point on one side of a line is also 180°.

angle 1 = 90 - 22 = 68°

180 = 59 + 68 + angle 2

angle 2 = 180 - 59 - 68 = 53°

180 = angle 2 + angle 3

angle 3 = 180 - 53 = 127°

180 = 90 + 59 + angle 4

angle 4 = 180 - 90 - 59 = 31°
