Answer to 3 is 441
answer to 4 is 12.4 (using pythagorem theorem which is A squared plus B squared equals C squared)
Answer:
4 feet long
Step-by-step explanation:
Pythagorean Theorem: + =
In this problem, a and b are the legs of the triangle, while c is the hypotenuse
Plugging the values of and to the equation you get:
5 + 11 =
Therefore, = 16, and by taking the square root you find that c, or the hypotenuse, must equal 4.
