Question 197027
<font face="Garamond" size="+2">


Let <b><i>x</i></b> represent the length of the longest side, then


The shortest side must be:  *[tex \LARGE \frac{x}{2} + 15]


and the third side must be:  *[tex \LARGE x - 4]


The perimeter is the sum of the lengths of the sides, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x + \left(\frac{x}{2} + 15\right) + \left(x - 4\right) = 121]


Solve for <b><i>x</i></b> to get the longest side, then the other two sides are simple calculations from the given relationships.
