A HELICOPTER MEASURES THE ANGLE OF DEPRESSION OF A CAR IN 11° (7/36). IF THE HELICOPTER IS AT 1500 FEET ON THE LEVEL OF THE ROAD, DETERMINE WHETHER THE CAR IS LOCATED FROM A POINT IN THE ROAD DIRECTLY BELOW THE HELICOPTER.

$$\large tan 11°=\frac{7}{36}=\frac{1500ft}{x}\\\large x=\frac{36\cdot 1500ft}{7}$$

$$\large x=7714.286ft$$

$$The \ car \ is \ 7714 ft \ from \ the \ base \ of \ the \ helicopter.$$
