Given:
The height of the kite from the ground = 60 yards
The length of the string of the kite = 100 yards.
To find the distance from Megan to the point on the ground directly below the kite.
Formula
By Pythagoras theorem for a right angle triangle we get,
where, h be the hypotenuse, b be the base, l be the another side along right angle.
Now,
Here, putting l = 60 and h = 100 we get,
=
Here we will take b = 80 because the length cannot be measured in negative.
Hence, the distance from Megan to the point on the ground directly below the kite is 80 yard.
Thus, Option D is the correct answer.
