Question

1
A blimp provides aerial television views of a tennis game. The television camera sights the stadium at a 9° angle of depression. The altitude of the blimp is 300m. What is the​ line-of-sight distance from the television camera to the base of the stadium​? Round to the nearest hundred meters.
9 °
300 m

Answer 1

The​ line-of-sight distance from the television camera to the base of the stadium​ is 1918.16 meters

What is a right triangle?

A right triangle has one of its angles as 90 degrees.

Therefore, the angles and side can be found using trigonometric ratios.

Hence, the​ line-of-sight distance from the television camera to the base of the stadium​ is hypotenuse side of the right triangle formed.

sin 9° = opposite / hypotenuse

sin 9° = 300 / h

h = 300 / sin 9

h = 300 / 0.15643446504

h = 1918.15856777

h = 1918.16 meters
