<PRE><B>Question 504107</B>
The perimeter of a triangle is 93 centimeters. 
If two sides are equally long and the third side is 9 centimeters longer than the others, find the lengths of the three sides.
:
Let x = the length of the equal sides
then
(x+9) = the length of the 3rd side
:
2x + (x+9) = 93
3x = 93 - 9
3x = 84
x = {{{84/3}}}
x = 28 is the length of the equal sides
and
28+9 = 37 is the length of the 3rd side</PRE>
