I believe the answer is 19.2 because you would have to do paythag. = a^2+b^2=c2 in this case it would be 7^2 + 10^2 = c From there you would get the answer of 149, and you would have to square root it. When you square root 149 you get 12.2 12.2 + 7 = 19.2 You would add them together because you want to know the height before it broke.
