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:
[tex]tan(41)=\frac{12}{x} \\12=x*tan(41)\\x=\frac{12}{tan(41)} \\x=13.80[/tex]
Answer: 13.8 (rounded to nearest tenth)
Hope that helps!
