Question 404031
An isosceles triangle has two equal An isosceles triangle has two equal
sides. 
If the shortest side of an isosceles triangle is 2 ft less
than one of the equal sides and the perimeter is 13 ft, then
what are the lengths of the sides?
---
Let the length of each equal side be "x":
Then the 3rd side has length = "x-2".
----
Equation:
Perimeter = side + side + side
13 = x + x + x-2
---
3x = 15
x = 5
----
Each equal side has length 5 ft
The 3rd side has length x-2 = 3 ft
