1.	233. Atower is 503 m high. The angle of elevation of its top from a point 50 maway from its foot has measureA. 45 B. 60 C. 30 D. 15
Answer» As height of tower is 50√3 m Distance of observer 50 m In a right angle triangle perpendicular and base is given. and we know that from trigonometric ratio tan thetha = perpendicular/ base tan thetha = 50√3/50tan thetha = √3 angle of elevation = tan-1 (√3)angle of elevation = 60°

Answer»

As height of tower is 50√3 m

Distance of observer 50 m

In a right angle triangle perpendicular and base is given.

and we know that from trigonometric ratio

tan thetha = perpendicular/ base

tan thetha = 50√3/50tan thetha = √3

angle of elevation = tan-1 (√3)angle of elevation = 60°
