A spherical balloon of radius 1 m subtends an angle of 60∘ at the eye of an observer. If the angle of elevation of its centre is 45∘ , what is the height of the centre of the balloon?
Assume that the eye of observer is at level ground.
1
100 cm
2
\(100\sqrt 2 \) cm
3
\(\frac{{100}}{3}\sqrt 3 \) cm
4
\(100\sqrt 3 \) cm
