Answer 1

Given :  A balloon’s thread  is 13m long and  reaches a window 12 m  above the ground

To Find : the distance of the nail  to which balloon is tied  from base of the wall.​

Solution:

A balloon’s thread  is 13m long

This would be hypotenuse of triangle

H = 13 m

reaches a window 12 m  above the ground.

This would be perpendicular height  P = 12 m

the distance of the nail  to which balloon is tied  from base of the wall.​

This would be Base  = B

Applying Pythagoras theorem

H² = P² + B²

=> 13² = 12² + B²

=> 169 = 144 + B²

=> B² = 25

=> B = 5    

distance of the nail  to which balloon is tied  from base of the wall.​ = 5 m
