the perimeter of a certain iscoleles right triangle is 16 + 16 sqrt 2. What is the length of the hypotenuse?
a. 8
b. 16
c 6 - sqrt 2
d. 8 - sqrt 2
e. 16 - sqrt 2.
I'm confused because the special properties of a 90-45-45 rt. triangle says that the sides are side, side, side sqrt 2. (which is the hypotenuse) so I'm confused.
OA is b. please explain why.
