Answer:

your answer is 9.7 feet

Step-by-step explanation:

you apply Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex] since you are looking for height you can subsitute x for a or b and since 12 is the largest number this will be your c which is your hypotneuse and 7 will be subsituted as a or b depending on what letter you used as your x value [tex]7^{2} +b^{2} =`12^{2}[/tex] is equal too 49 +b^2 =144 you then subtract 49 on both sides to isolate your x (b) and this gets you 95 and then you find the square root of 95 which is 9.7
