Question

A student extended the rope of the flag pole to the ground.the end of the rope is 3 meters away from the fool of the flagpole . if the rope 18 meters long compute the heigth of the flagpole in two decimal places. formula​

Answer 1

Answer:

Step-by-step explanation:

It is a right angle triangle

So, ATQ

hypotenuse here is rope which is 18m long

base is 3m

according to Pythagoras theorem

hy^2 = p^2 + b^2

18^2 = p^2 + 3^2

324 =  p^2 + 9

324 - 9 = p^2

315 = p^2

$\sqrt{315} = p\\p = 17.75 (approx)$
