Given l = 30 inches, w = 20 inches, h = 18 inches, and x = 36.1 inches, find the length of d. Round the answer to the nearest tenth.
We can use the Pythagorean theorem to find the length of d. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).
In this case, the length of d would be the hypotenuse of a right triangle with sides of length l, w, and d. We can set up the equation as follows:
d^2 = l^2 + w^2
Plugging in the given values, we get:
d^2 = 30^2 + 20^2
d^2 = 900 + 400
d^2 = 1300
To solve for d, we take the square root of both sides:
d = √1300
d ≈ 36.1 inches
So the length of d is approximately 36.1 inches.
