One side of a triangle is 13 feet shorter than the second side. The third side is 1 feet longer than the second side. The perimeter of a triangle is 45 feet. Find the length of each side

let second side be x

then first side = x-13

third side= x+1

now

perimeter of triangle = 45

x-13+x+x+1=45

3x=57

x=19

first side = x-13= 19-13=6

third side= x+1=19+1=20
