The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

H = 50\ yards\\B = 35\ yards

We have to find the perpendicular

Using pythagoras theorem,

H^2 = B^2 + P^2

Putting the values

(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\

Taking square root on both sides

\sqrt{P^2} = \sqrt{1275}\\P= 35.707

Hence,

The kite is directly 35.707 yards high above Erika
