Question

Use the Pythagorean Theorem to find the length of the hypotenuse in the triangle below.

The figure shows a right triangle with legs marked 40 and 9.

Answer 1

Answer: Hypotenuse is 41

Answer 2

41

Explanation:

The Pythagorean Theorem:

`x^2+y^2=z^2`

where x and y are two legs, and z is the hypotenuse

Plugging this in, we have

`40^2 + 9^2 = 1681\\√(1681)=41`
