Question 265691
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the measure of one of the equal sides.  Then the remaining side must measure *[tex \Large 1.5x\ -\ 3]


The perimeter of any polygon is the sum of the measures of the sides, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ 1.5x\ -\ 3\ =\ 28.5]


Solve for *[tex \Large x] to get the measure of the two equal sides and the third side is a simple calculation from there.
