$sin(x) = \frac{15}{40}\\x = 22^{\circ}$

To isolate x, I put $sin$ to the other side of the equations and changed it to $sin^{-1}$

$tan(x) = \frac{12.5}{8}\\x = 57^{\circ}$

This is pretty much the same as the last one, I put $tan$ to the other side of the equation and changed it to $tan^{-1}$

A few of these photos are not showing. Can you check them? I would also like a short explanation on HOW to solve each.
