Question If a 45°-45°-90° triangle has a hypotenuse length of 72, what is the length of each leg of the triangle?
Select the correct answer.
O 7V2
O 7
O V2
O 2

B

Step-by-step explanation:

We are given that a 45-45-90 triangle has a hypotenuse of .

In a 45-45-90 triangle, the legs are congruent. Therefore we can use the Pythagorean Theorem to solve.

        [combine like terms]

              [square root both sides]

                [divide both sides by root 2]

Now, we know that a leg is length 7, which is B.                

answer:   y=2x-3
