A spherical balloon of radius r subtends an angle of 60° at the eye of an observer. If the angle of elevation of its centre is 45° from the same point, then prove that height of the centre of the balloon is √2 times its radius.
Hey ,i watch your channel but i want that you should make video on yourself ( your channel reason,your passion, your background, biography... All) Will you make for just me .....( Because i highly inspired by you ..cuz i also love to solve problems..and i found out you who feels like genius.......
