Given:
The angle of elevation from a ship in the ocean to an airplane overhead is 25°. If the horizontal distance in the ocean between the boat and the plane is 75 yards.
Required:
To find the height of the plane.
Explanation:
Now consider the figure
From the given figure, the height is given by
[tex]\begin{gathered} \tan25=\frac{x}{75} \\ \\ 0.4663=\frac{x}{75} \\ \\ x=0.4663\times75 \\ \\ x=34.9 \\ \\ x=35yards \end{gathered}[/tex]Final Answer:
The height of the plane is 35 yards.
