Question

Please help me thanks!

Answer 1

Answer: See the screenshot below.

Explanation:

We'll be using these trig functions

• sine = opposite/hypotenuse
• cosine = adjacent/hypotenuse
• tangent = opposite/adjacent

The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as $\sin^{-1}$ on many calculators.

The decimal results are approximate.
