the lengths of the sides of a triangle are x, x - 5, 3x centimeters. if the perimeter is 80 centimeters, what is the value for x?

x= 17cm

Step-by-step explanation:

given:

sides of a triangle:

x, x-5, 3x

perimeter= 80cm

perimeter of a triangle= side + side + side

80 = x + (x-5) + (3x)

80 = x + x + 3x -5 >(rearranging the like terms together)

80 = 5x - 5

80+5 = 5x

85 = 5x

85/5 = x

17cm = x
