Ok, there's our diagram
We can see that the angle opposite the height h is going to be 35 degrees, since they are both alternate angles.
thus to find h, we use the sine relation
[tex]\begin{gathered} \frac{h}{7}=\sin 35 \\ h=7\sin 35=\text{ 4.015 miles }\approx\text{ 4.0 miles to the nearest tenth} \end{gathered}[/tex]
