Question 223247
<font face="Garamond" size="+2">


If two angles are complementary, then the sum of their measures is 90 degrees or *[tex \Large \frac{\pi}{2}] radians.  So the complement of an angle that measures *[tex \Large 3x+12] is *[tex \Large 90 - (3x + 12)] degrees or *[tex \Large \frac{\pi}{2} - (3x + 12)] radians.  The sum of the measures of supplementary angles is 180 degrees or *[tex \Large \pi] radians, otherwise the expressions are the same.
