A person observes that the angle of elevation at the top of a pole of height 5 meters is 30°. Then the distance of the person from the pole is:

If θ is an acute angle and tan θ + cot θ = 2, then the value of \(tan^{200} θ + cot^{200} θ\) is:

If \(sin α + csc α = tan{\pi\over 3}\), then the value of (sin^{3}α + csc^{3}α) is equal to:

A train crosses a platform 180 m long in 60 sec at a speed of 72 km/h. The time taken by the train to cross an electric pole is:
