Answers
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 the base of the wall.
Solution:
Let's assume,
AB = 12 m = the vertical distance between the window and the ground i.e., the perpendicular height
AC = 13 m = the length of the balloon's thread which is tied at the point C i.e., the hypotenuse
BC = the distance of the nail to which balloon is tied from the base of the wall i.e., the base
Now, considering Δ ABC, using the Pythagoras theorem, we get
substituting the values of AB & AC, we get
Thus, the distance of the nail to which balloon is tied from the base of the wall is 5 m.
