Question

If a tower 30 m high cast a shadow 10√3 m long on the grounf then what is the angle of elevation of the sun

Answer 1

height of tower, altitude =30 m
length if shadow,base=10√3
considering a right angled triangle.
tan©=Altitude/base=30/10√3=3/√3=√3
so,©=60°
is the required elevation of the sun.
