A blimp provides aerial television views of a baseball game. The television camera sights the stadium at a 7degrees 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.

The line of sight distance [call it D ] is the  hypotenuse of a right  triangle

 

We  know the angle   and the  altitude of the  blimp is the opposite side to this angle

 

Thus...we can use the sine here because it relates the opposite side and the hypotenuse

 

sin 7°  =   300 / D      rearrange as

 

D = 300 / sin 7°  ≈  2461.65  m
