Question

The length of shadow of a pole 50m high is 50root 3 find the sun altitude

Answer 1

Answer:

Here the length of pole is 50m

and shadow of pole is 50 root 3:

See the attached diagram:

Now you need to calculate altitude of sun (beta) is;

tan(beta)=50/50root3=1/root3 (50 is divided by 50, that is 1)

beta=inverse of tan (1/root3), we know tan30=(1/root3)

beta=30 degree. This is sun altitude
