Question

If a tower 30 m high casts a shadow of 10 root 3 m long on the ground then what is the angle of elevation of the sun

Answer 1

AB = 30 m

BC = 10 root 3

Hope it helps you!

Answer 2

perpendicular=30
base=10root3
p/b=tan A
tan A=30/10root3
tanA=3/root3
multiply by root3/root3
tanA=3root3/3
tanA=root3
tanA=tan60


so angle of elevation of sun is 60
