Answer 2

i would use the pythagorean therm right?

Answer 3

7^2+x^2=17^2?
49+x^2=196
x^2=147
x=7sqrt3
is that right?

Answer 4

yes

Answer 5

okay well how do i get an answer in feet?

Answer 7

no its not cuz i only have these answers to choose from
4.9 ft

15.5 ft

18.4 ft

9.9 ft

Answer 8

\(7\sqrt3 \text{ft}\) is the answer.
\(\sqrt3\) is a number between .. what and what? even with rough bounds you should be able to find the answer
