To solve this, we need to use our trigonometric equations
⇒ look at the diagram attached
Let's examine what the problem wants:
- the length of the side adjacent to the 58-degree angle
Let's examine what the problem gives us:
- the length of the side opposite to the 58-degree angle
- the angle that has a measure of 58-degrees
Let's solve:

Answer: 13.8 (rounded to nearest tenth)
Hope that helps!
