Question

(PLEASE ANSWER + BRAINLIEST ANSWER!!!)

Answer 1

Use the Pythagorean Theorem to solve this question.
I use the ^ to tell that it is squared 
so 9 squared +3 squared =x squared 

9^2+3^2=x^2
x^2= radical 90
x ≈ 9.5 feet

Answer 2

We can use the Pythagorean Theorem:
9² + 3² = x²
We get x≈9.5 feet.
