A kite is flying with a string of length 200 m. If the thread makes an angle of 300 with the ground, find the distance of the kite from the ground level. (Here, assume the string is along a straight line)
Solution:
Let h be the height of the kite from the ground
level.
In, ∆ ABC, AC be the length of the string,
Given that ∠
CAB = 300 and AC = 200 m.
In the right angled triangle, ∆ CAB
sin300 = h/200
∴
½ = h/200
∴
h = 200/2
∴
h = 100 m.
Hence the height of the kite from the
ground level is 100 m.
