Complete Question:
Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.
Write an equation using the Pythagorean Theorem to find the value of x.  
How far are Ava's feet from the balloon?
Answer:
Ava's feet is 17ft away from the balloon
Step-by-step explanation:
Given


The attached image represents the scenario
Using Pythagoras theorem (from the attachment), we have:



Take square roots of both sides


 
        
             
        
        
        
X would be 0 and y would be 2 so it would be (0,2)
        
             
        
        
        
Well, it should be 45 because 1/3 of the game would be 15 and 15+15 is 30 (2/3rds cost), so 15+15+15, 45, would be the full cost of the game
