प्रश्न
A man goes 18 m due east and then 24 m due north. Find the distance of his current position from the starting point?
उत्तर
Let the initial position of the man be “O” and his final position be “B”.
By Pythagoras theorem
In the right ∆OAB,
OB2 = OA2 + AB2
= 182 + 242
= 324 + 576 = 900
OB = `sqrt(900)` = 30
The distance of his current position is 30 m
