Three baseball players are playing catch. Simon is directly south of Kaylee and directly west

of Whitney. Simon and Whitney are 30 feet apart and Whitney and Kaylee are 34 feet apart.
How far apart are Simon and Kaylee?

Answer: 22.27 feet or 31.68 feet, depending on which direction they are throwing the ball.

Explanation:

Let's call the distance between Simon and Kaylee "x". We can use the Pythagorean theorem to set up two equations based on the given distances:

x^2 + 30^2 = d1^2 (where d1 is the distance between Simon and Whitney)

x^2 + 34^2 = d2^2 (where d2 is the distance between Kaylee and Whitney)

We can solve for d1 and d2 by taking the square root of both sides of each equation:

d1 = sqrt(x^2 + 900)

d2 = sqrt(x^2 + 1156)

Since we know that d1 + d2 = 30 + 34 = 64 feet (the total distance between Simon and Kaylee), we can substitute the expressions for d1 and d2 into this equation:

sqrt(x^2 + 900) + sqrt(x^2 + 1156) = 64

We can square both sides of the equation to eliminate the square roots:

x^2 + 900 + 2sqrt((x^2 + 900)(x^2 + 1156)) + x^2 + 1156 = 4096

Simplifying:

2x^2 + 2056 + 2sqrt((x^2 + 900)(x^2 + 1156)) = 4096

Subtracting 2056 from both sides:

2x^2 + 2sqrt((x^2 + 900)(x^2 + 1156)) = 2040

Dividing both sides by 2:

x^2 + sqrt((x^2 + 900)(x^2 + 1156)) = 1020

Squaring both sides again to eliminate the square root:

x^4 + 2052x^2 + 656100 = 1040400

Simplifying:

x^4 + 2052x^2 - 384300 = 0

This is a quadratic equation in x^2. We can solve for x^2 using the quadratic formula:

x^2 = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 2052, and c = -384300. Plugging in these values:

x^2 = (-2052 ± sqrt(2052^2 - 4(1)(-384300))) / 2(1)

x^2 = (-2052 ± sqrt(9248256)) / 2

x^2 = (-2052 ± 3044) / 2

x^2 = 496 or x^2 = 1004

Taking the positive square root of both sides (since x represents a distance, it must be positive), we get:

x = sqrt(496) or x = sqrt(1004)

x ≈ 22.27 feet or x ≈ 31.68 feet

So the distance between Simon and Kaylee is approximately 22.27 feet or 31.68 feet, depending on which direction they are throwing the ball.

Answer:

16 feet

Explanation:


a^(2) +
b^(2) =
c^(2)


30^(2) +
b^(2) =
34^(2)

900 +
b^(2) = 1156

900 - 900 +
b^(2) = 1156 - 900


b^(2) = 256


\sqrt{b^(2) } =
√(256)

b = 16
