Can someone please explain how to solve 13?

Hello!
Everything you've done so far seems to be correct. However, you need to get rid of the sin. To do this, use s[tex]sin^{-1}[/tex].
This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.
When you run [tex]sin^{-1}(1/5)[/tex] through a calculator, you get about 11.537 degrees, or θ = 11.537.
To verify this, all you need to do is run sin (11.537), and the calculator returns 0.2, which is what we're looking for.
Hope this helps!
