Balloon Connected Meteorological Ground Station Cable Length Inclined 60в° Horizontal

A balloon is connected to a meteorological ground station by a cable of length 215 m inclined at 60° … Assume that there is no…

Answers:

Let A be the position of the balloon.
In rt.△ABC,
sin 60° = AB/AC
AB = 215 sin 60° 
AB = 215 × √3/2
= 215 × 1.73/2
= 186 m
Therefore the height of the balloon from the ground is 186 m.
