Question

height of a tower is 100 m.When the angle of elevation of the sun is 30°.then what will be the length of shadow of the tower.​

Answer 1

Answer:

tan @ = height / base

tan 30= 1/ root 3

1/root 3 = 100/ length of the shadow

length of the shadow = 100 x root 3 (value of root 3 = 1.732)

                                    = 100 x 1.732

                                    = 173.2 m
