Question
From a point "A" on the ground, the angle of elevation
to the top of a tower measuring 12 meters in height is 30°. Determine the horizontal distance between point "A" and the base of the tower.Solution
Let BC = length of the tower = 12 metres
In right triangle ABC;
tan30 o = (BC/AB)
So, (1/√3) = (12/AB)
So, AB = 12√3 m
