Answer 1

In this case, we must use our trigonometric equations to help us solve this problem:

⇒ look at the diagram attached

Let's examine what the problem wants:

• side adjacent to the 41-degree angle

Let's examine what the problem gives us:

• length of the side opposite the 41-degree angle
• one angle which has a measure of 41 degrees

Let's solve:

`tan(41)=(12)/(x) \\12=x*tan(41)\\x=(12)/(tan(41)) \\x=13.80`

Answer: 13.8 (rounded to nearest tenth)

Hope that helps!
