A person gets on a Ferris wheel at the starting point. The starting point is 15 feet off the ground. The Ferris wheel has a radi

<h2>Answer:</h2>

$\boxed{\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}$

<h2>Explanation:</h2>

<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle $11\pi /2=165^{\circ}$ , therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

$\overline{BC}=\overline{AB}sin(75^{\circ})=50sin(75^{\circ})=\frac{25}{2}(\sqrt{6}+\sqrt{2})$

Finally, the height is:

$H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+15+50 \\ \\ \boxed{H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}$

I wrote down 3 different positive whole numbers that add 96. the sum of any 2 is divisible by the third.

il63 [147K]

This question is really simple if you focus on this part

“The sum of any two is divisible by the third”

<span>⟹⟹</span> Pairwise, the numbers must have a GCD greater than one.

Let this GCD be <span>xx</span>.

The first three easiest numbers I can think of are <span><span>x,2x</span><span>x,2x</span></span> and <span><span>3x</span><span>3x</span></span>

Because

<span><span>gcd(x,2x)=gcd(2x,3x)=gcd(3x,x)=x</span><span>gcd(x,2x)=gcd(2x,3x)=gcd(3x,x)=x</span></span>

The numbers sum to <span>9696</span>

<span><span>⟹x+2x+3x=96</span><span>⟹x+2x+3x=96</span></span>

<span><span>⟹6x=96</span><span>⟹6x=96</span></span>

<span><span>⟹x=16</span><span>⟹x=16</span></span>

The largest number is <span><span>3x=3×16=48</span><span>3x=3×16=48</span></span>

Thanks for the A2A
