The angles labeled 22, 1, and 2 are part of a triangle. 1 is a 90 degree angle.
So, 2 is 180-90-22=68 degrees.
3 is 180-68=112 degrees, since it forms a straight line if joined with angle 2.
4 is also 112 degrees since it is vertical with 3. .
5 is 180-112=68 because it makes a straight line with 4.
And so on
