What is the hypotenuse? (Hint: What side of the triangle is the biggest? What side of the triangle is opposite the right angle?)

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle

Step-by-step explanation:

The hypotenuse of a right triangle is always the side opposite the right angle.

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:

d
