Where does the sun rise on october 8? (select] where does the sun set on june 21? [select] (specify direction as n, s, e, w, ne, nw, se, or sw)

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
