Question 334777
<font face="Garamond" size="+2">


The sum of the measures of an angle and its complement is  *[tex \Large 90^\circ].  So the measure of the complement of an angle that measures *[tex \Large x] is *[tex \Large 90\ -\ x].


The sum of the measures of an angle and its supplement is  *[tex \Large 180^\circ].  So the measure of the supplement of an angle that measures *[tex \Large x] is *[tex \Large 180\ -\ x].


Add the two measures and divide by 2.
