What is the answer for x

x=20

Step-by-step explanation:

This is a right triangle, so we can use the pythagorean theorem to help us find x.

The the theorem states that the sum of the legs squared is equal to the length of the hypotenuse squared.

Thus, our equation is:

x^2+48^2=52^2

Simplify.

x^2+2304=2704

Subtract 2304 from both sides.

x^2=400

Find the square root of both sides.

x=20

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
