Question : 14 of 40

Marks: +1, -0

A father watches his son flying a kite from a distance of 40 m. The kite is at a height of 120 metres directly above the son. How far is the kite from the father?

126.49 m
122.49 m
124.49 m
All of the above
None of these

Solution:

In Δ ABC,

H^2 = P^2 + B^2

= (120)^2 + (40)^2

= 14,400 + 1,600 = 16,000

H=√16000=126.49m
