Angle of elevation of the top of a building from a point P on the horizontal is 30°. If the point P is 48 m away from the foot of the building, then what is the height of the building?

$16 \sqrt{3}$ m

When we have the angle 30^o

Then we can calculate the various measurements with the help of the triangle given above.

So, √3 = 48

h = 1 = $16 \sqrt{3}$ m
