Find the distance between the helicopter and the ship

###### Advertisements

#### Solution

From the figure AS is the distance between the helicopter and the ship.

∆APS is a right angled triangle, by Pythagoras theorem,

AS^{2} = AP^{2} + PS^{2}

= 80^{2} + 150^{2} = 6400 + 22500

= 28900

= 170^{2}

∴ The distance between the helicopter and the ship is 170 m
