Question

1) A balloon is connected to metro logical ground station by a cable of length
215m inclined at 60° to the horizontal. Determine the height of balloon from the
ground.​

Answer 1

Answer:-

Let the height of the balloon from the ground = h m

Given, the length of the cable = 215 m and the inclination of the cable is 60o.

In ΔABC

sin 60o = AB/ AC

√3/2 = h/215

h = 215√3/2 = 185.9

Hence, the height of the balloon from the ground is 186 m (approx).
