To solve for this, we need to use Pythagorean Theorum. Pythagorean Theorum is when we add the squares of the legs (A & B) to solve for the hypotenuse (C) or the side that's across from the 90 degree angle. The formula for Pythagorean Theorum is A^2 + B^2 = C^2.
We have our two leg lengths, 15 and 36 (A & B). Square 15 and 36. 15^2 = 225 36^2 = 1,296
Now that we have our side lengths, let's add them up. 225 + 1,296 = 1,521.
Now, to solve for C, we need to square root our sum.
Mean or Average is all of the sums divided by how many of the choices are there, so all of 10,126+9,99+12,398+12,007+4567=49097 and divided by all the choices you have which is 5 is 9819.4
