In the diagram, angle k is an exterior angle. Angles c, g, o ,s, and w are corresponding angles. They are in the same position, but on different lines. Corresponding angles are equal. Therefore they are all 89 degrees.
A straight line measures 180 degrees.
Angle i is on the same line as angle k. Therefore is angle k is 89, angle i = (180-89) = 91.
Using this same theory the following angles are on the same line and measure 180 degrees:
Angle c = 89, Angle a = 91
Angle g = 89, Angle e = 91
Angle k = 89, Angle i = 91
Angle o = 89, Angle m = 91
Angle s = 89, Angle q = 91
Angle w = 89, Angle u = 91
The solution to your question derived from the information above is as follows;
Angle s = 89
Angle e= 91
Angle q= 91
Angle u= 91
Angle o=89
Angle i=91
Angle a = 91
