5 ft
x

Assuming you're referring to the sides of a right triangle, the missing side X would be 12.

Step-by-step explanation:

The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. is 169, is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.

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
