One side of a triangle is 9 feet shorter than the second side. the third side is 2 feet longer than the second side. the perimeter of a triangle is 38 feet. find the length of each side.

First side - 6

Second side - 15

Third side - 17

Step-by-step explanation:

The triangle has three sides and when added together they equal 38.

So if the second side is x, then the other sides are x-9 and x+2.

So x+x - 9 +x+2 = 38.

3x-7 = 38

3x = 45

x=15 so the second side is 15.

So the first side is x-9 = 15-9 = 6

The third side is x+2 = 15+2=17

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

add 5 subtract 1
