Question

Can someone please answer. There is one problem. There's a picture. Thank you!

Answer 1

The answer is the second option, 52°.

To find the answer, I plugged the different answer options into my calculator until I found the one that was equivalent to what the question was asking for.

Alternatively, you could take the inverse cosine of 0.616 to solve for the angle whose cosine is equivalent to that number.
