Answer :
Answer:
420 feet
Step-by-step explanation:
GIVEN: The High Roller wheel in Las Vegas has a diameter of [tex]520[/tex] feet and its base is [tex]30[/tex] feet off the ground. You board a gondola on the wheel and rotate [tex]240[/tex] degrees counterclockwise before the wheel temporarily stops.
TO FIND: How high above the ground are you when the wheel stops?
SOLUTION:
Consider the figure attached.
As wheel rotate counter clockwise [tex]240^{\circ}[/tex], its current position is [tex]120^{\circ}[/tex] clock wise.
Total height [tex]=260+30+h\rightarrow290+h[/tex]
Calculating value of [tex]h[/tex]
[tex]\sin 30^{\circ}=\frac{h}{260}\impliesh=260\sin30^{\circ}[/tex]
[tex]\implies h=260\times\frac{1}{2}=130feet[/tex]
Total height [tex]=290+130[/tex] feet
[tex]=420\text{ feet}[/tex]
Hence total height is 420 feet
