Angle c is the complement of angle 1, and angle s is the supplement of angle 1. what is the difference between the measures of angle s and angle c

Complementary angles = 90 degrees

 Supplementary angles = 180 degrees

 it depends on where angle S and angle C are located with each other

they could be 180-90 = 90 degrees apart

or 180+90 = 270 degrees apart.

 You don't show a picture of the relationship of the angles.

 but based on their relationship with angle 1, they are 270 degrees apart
