The measure of b and c from the diagram is 122 and 58 degrees
Determining the measure of angles a and b
The measure of angle on a straight line is 180 degrees.
b + 58 = 180
b = 180 - 58
b = 122 degrees
The measure of c is 58 degrees (vertically opposite angles).
Hence the measure of b and c from the diagram is 122 and 58 degrees
