x = 14.3

Step-by-step explanation:

To find one of the sides, we can use the pythagorean theorem:

a² + b² = c²

a² = c² - b²

a = √c² -b²

a = √(20)² -( 14)²

a = 14.3

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:
