Question

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

Answer 1

given
a tower height = 30

it's shadow is = 10 root 3

from above in a right angled triangle one of the side is 30 and other side is 10 root 3

tan deta = opposite/adjacent

$\frac{30}{10 \sqrt{3} }$
$\frac{3}{ \sqrt{3} }$

$\sqrt{3}$

then

tan deta = tan 60

deta = 60
