Answer:

x = 9

Explanation:

→You can use the Pythagorean Theorem to solve:


a^2+b^2=c^2

→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:


40^2+b^2=41^2


1600+b^2 = 1681

→Subtract 1600 from both sides:


b^2=81

→To get "b," by itself, square root both sides, like so:


√(b^2) =√(81)

→81 is a perfect square meaning it has two factors that are identical.


b = 9
