Given I=30in., w=20in., h=18in., and x=36.1in., find the length of d. Round the answer to the nearest tenth.
To find the length of d, we can use the Pythagorean theorem. According to this theorem, in a right triangle, the square of the length of the hypotenuse (d) is equal to the sum of the squares of the lengths of the other two sides.
In this case, I will assume that d is the hypotenuse, and w and h are the other two sides of the right triangle. So we have:
d^2 = w^2 + h^2
Substituting the given values into the equation:
d^2 = 20^2 + 18^2
d^2 = 400 + 324
d^2 = 724
To find the length of d, we take the square root of both sides of the equation:
d = sqrt(724)
d ≈ 26.9
Therefore, the length of d is approximately 26.9 inches.
