I'll help you with this question :)

(however you should answer the other one you just posted)

 

We know the chopper is 630 meters above the highway, and the angle of depression is 27 degrees. We want to find how far along the highway the accident is. 

 

Below is the diagram, where x is the length of the highway

We see that \(\tan(27^\circ) = \frac{630}{x}\)

Therefore, \(x=\frac{630}{\tan(27^\circ)}\).

Plugging this into a calculator gives us \(\approx1236.44\)
