Question

What is the measure of the angle formed and the ground to the nearest tenth of a degree

Answer 1

Check the picture below.

`\sin( \theta )=\cfrac{\stackrel{opposite}{22.8}}{\underset{hypotenuse}{24}} \implies \sin^(-1)(~~\sin( \theta )~~) =\sin^(-1)\left( \cfrac{22.8}{24} \right) \\\\\\ \theta =\sin^(-1)\left( \cfrac{22.8}{24} \right)\implies \theta \approx 71.8^o`

Make sure your calculator is in Degree mode.
