Answer 2

Thus the length of the shadow is  x = 60 √3

Explanation:

We are given that:

• Height of pillar = 60 m
• Altitude of sun = 30 degree
• To Find: Length of the shadow

Solution:

tan (30°) = 60 / x

[Since tan (30°)  =  1 /√3]

Therefore

1 /√3 = 60 / x

x = 60 √3

Thus the length of the shadow is  x = 60 √3
