Find the length of the hypotenuse.<br><br><br><br> Use Pythagoras' theorem c2 = a2 + b2
melisa1 [442]
Answer: 26

Step-by-Step Explanation:

a = 10
b = 24
c = ?

Using Pythagoras Theorem,
c^2 = a^2 + b^2
c^2 = 10^2 + 24^2
c^2 = 100 + 576
c^2 = 676
=> c = √676 = 26

Hence, c = 26

Answer:

Joseph is correct

Step-by-step explanation:

I cannot see the options in the drop-down menus. Even though, Joseph is correct because the difference between the longest length (which is 12 ft) and shortest length (which is 9 1/2 ft) is 12 - 9 1/2 = 2 1/2 ft. It doesn't matter how many ropes measure those lengths.
