The angle of elevation of the top of a tower at a point on the ground 50m away from the foot of the tower is `45^0dot` Then the height of the tower (in metres) is

Explanation

Assume height of tower be ' h ' m.


`Rightarrow tan 45^{circ}=frac{Height}{Base}=frac{h}{30} `


`Rightarrow 1=frac{h}{30} `


`Rightarrow h=30 m`


Required answer is `30 m`.
