We want to know if the referee can hear the player's question. Let's start by looking at the diagram!
The referee's ear is 7 feet above the player's mouth. Now, we can draw a triangle with two sides measuring 7 feet and 24 feet. The missing side will be the distance between the referee's ear and the player's mouth. Let's do it!
Notice that the distance between the referee's ear and the player's mouth is the hypotenuse of a right triangle. Therefore, we can use the Pythagorean Theorem to find the length of the missing side. a^2+b^2=c^2 In this formula, a and b are the legs and c is the hypotenuse of a right triangle. Let's identify a, b, and c on the diagram.
a= 24, b= 7
