Use a calculator bruhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
A^2 + b^2 = c^2
8^2 + b^2 = 11^2
64 + b^2 = 121
b^2 = 121 - 64
b^2 = 57
b = sqrt 57
b = 7.54 rounds to 7.5 ft <==
14 pounds. Here is a easy way to solve exponents. For example, say there is a dolphin that is 10 to the 2nd power times more than 120. Just add 2 zeros and you will get 1,200!
