9-21.

Antonio’s friend Jessica was also on The Screamer when it broke. Her seat was $65$ feet above the ground. What was her seat’s angle of rotation? Is there more than one possibility?

The height of the triangle is $65'$ and the hypotenuse is $100'$.

$\sin \theta = \frac{65}{100}$

How many positions on The Screamer are $65'$ above the ground?

One point is at approximately $40.5°$.
