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?
Answer & explanation
Correct answer: option 3
When we have the angle 30o
Then we can calculate the various measurements with the help of the triangle given above.
So, √3 = 48
h = 1 = $16 \sqrt{3}$ m
