Question 937762: In an isoceles triangle, the length of the third side is 25% of one of the equal sides. Find the length of each side when perimeter is equal to 135 ft.
You can put this solution on YOUR website! x = length of third side
y = length of each equal side
---
x + 2y = 135
x = 0.25y
---
put the system of linear equations into standard form
---
x + 2y = 135
x - 0.25y = 0
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = length of third side = 15 ft
y = length of each equal side = 60 ft
