Two supplementary angles are in the ratio of 2 to 3. The number of degrees in the smaller angle is:
A. 18
B. 36
C. 54
D. 72
Supplementary angles add to 180ยบ. Represent the angles as 2x and 3x. 2x + 3x = 180 and 5x = 180 therefore x = 36.
BE CAREFUL!! The question asked for the smaller angle (2x). 2x = 72.'
