Question

Can someone please explain how to solve 13?

Answer 1

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$sin^{-1}$.

This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.

When you run $sin^{-1}(1/5)$ 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!
