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.
+128474 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
