Answer 1

$\huge\green{Heya!!!\:Mate}$

Solution:-

Height of the pole H1, = 10 m

Length of the shadow of the pole, X1 = 2 m

Height of the tower = H2 m

Length of the shadow of the tower, X2 = 60 m

Since, if the two shadows cast, that will form two triangles which will be similar. Therefore, the ratio of their corresponding sides will be equal.

Therefore.

H1/H2 = X1/X2

10/H2 = 2/60

H2 = 600/2

H2 = 300 m

Hence the height of the tower is 300 m.  Answer......
