Question

a plane is flying towards the fresno airport at the angle of depression of 35 degrees. If the airport is 7 miles away,how high in the sky is the plane when its starts its descend to the airport Draw a picture, label it, and round answer to the nearest tenth.

Answer 1

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

`\begin{gathered} (h)/(7)=\sin 35 \\ h=7\sin 35=\text{ 4.015 miles }\approx\text{ 4.0 miles to the nearest tenth} \end{gathered}`
