Question 250637
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the measure of the angle.  Then *[tex \Large 9x] must be the measure of the supplement.  The sum of the measures of an angle and its supplement is 180.  Hence:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ 9x\ =\ 180]


Just solve for *[tex \Large x]
