| This is grim. The whole point of Pythagoras' theorem is that it is an exact result, but most of these answers are not. Using your lengths, the "right angles" are 90, 90, 90.006, 90.446, 90, 90, 90.128, 89.982, 92.579, 89.749, 89.982 degrees respectively (all to 3 d.p. except where exact). If the intention is to see whether we can approximate these hypotenuses using a calculator, then that's a pretty pointless quiz. |
