Question

Some small guns are mounted at the top of a police van which make an angle 30° with horizontal for security purpose. If a muzzle fired from gun covered a distance of 184 m, then find the height of last point of distance covered by muzzle with surface of earth.

Answer 1

sin θ = \(\frac { AC }{ AB }\) (Formula)

⇒ AC = AB sin θ

⇒ AC = 184 sin 30°

⇒ AC = 184 × \(\frac { 1 }{ 2 }\)

⇒ AC = 92 m
