Question 237726
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the measure of the smallest angle.  Then the measure of the largest angle must be *[tex \Large 3x] and the measure of the third angle must be *[tex \Large x\ +\ 20].  Since the sum of the measures of the three angles of any triangle is 180°, we can write:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ (x\ +\ 20)\ + 3x\ =\ 180]


Solve for *[tex \Large x] to get the measure of the smallest angle.  Multiply that by 3 to get the measure of the largest, and add 20 to it to get the measure of the third one.
