Question

A flag pole 18 m high casts a shadow 9.6 m long. What is the distance of the top of the pole from the far end of the shadow?

Options

• 20 metres

• 20.04 metres

• 20.4 metres

• 24 metres

Answer 1

20.4 metres

Explanation:

Given, Flag height = 18 m

Shadow length = 9.6 m

Distance between top of flag and end of shadow = x² = 18² + 9.6²

= 324 + 92.16

= 416.16

= (20.4)²

x = 20.4 m
