Question 357772
A triangular sail has two sides the same length.  The third side is 5 ft shorter than either of the equal sides.  The perimeter of the sail is 61ft.  How long is the shortest side
..
let the two equal sides be x each
the third side = x-5
perimeter = 61 feet
...
x+x+x-5 = 61
3x-5 = 61
add 5
3x=66
/3
x=66/3
x=22 feet
..
shorter side = 22-5 = 17 feet.
