In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call
`x`) and the length of the hypotenuse. This sets you up with the relation


`\sin2^\circ=\frac x{1600}\implies x\approx55.84\text{ m}`

In 23, you're given a similar situation, except now you're looking for the angle (I'll call it
`\theta`) in the triangle opposite the side denoting the height of the airplane. So this time,


`\sin\theta=(1500)/(5000)=\frac3{10}\implies\theta=\arcsin\frac3{10}\approx17.46^\circ`
