30 °

with the ground and covers a distance of 184 m.
We construct a diagram for the given description of the problem.
Question Image

Using the identity

sin θ = Perpendicular Hypotenuse

Δ A B C

sin θ = AB AC

Now substituting

θ

30 °

, and AC=184 in the equation

sin θ = AB AC

⇒ sin 30 ° = AB 184 ⇒ A B = 12184 [∵ sin 30 ° = 12] ⇒ A B = 92 m

Thus the height of the aeroplane above the ground is

92

m.
Therefore the correct option is 3.
