Question
Raju is positioned 30 meters away from the base of a
tower. From his standing point, the angle of elevation to the top of the tower is 45°. Determine the height of the tower.Solution
Let the height of tower = AC and position of Rajat is 'B'.
In DABC,
tan45o = (AC/BC) = (AC/30)
Or, 1 = (AC/30)
Or, AC = 30
So, height of the tower = 30 metres
