The shadow of a tree on the ground is found to be 20m when the sun rays meet the ground at an angle of 30 degree. Find the height of the tree

Answer 1

You can't get a trig problem more basic and fundamental than that,
somebody really has to learn those basics ....

make your sketch,
let the height of the tree be h

in your right-angled triangle, in terms of the 30° angle
h is the opposite, and 20 is the adjacent

tan 30° = opposite / adjacent = h/20
h = 20tan30°
= .....
