Q:

A kite is flying in the sky. The length of string between a point on the ground and kite is 420 m. The angle of elevation of string with the ground is 30^o. Assuming that there is no slack in the string, then what is the height (in metres) of the kite?

• 1
  $$ {210\sqrt{3}}$$
• 2
  240
• 3
  $$ {240\sqrt{3}}$$
• 4
