jimthompson5910 (jim_thompson5910):

if you don't have a calculator, you can either type "arctan(1/3)" without quotes into google to get 0.321750554 radians or you can type "arctan(1/3)" without quotes into wolfram alpha to get the same answer

jimthompson5910 (jim_thompson5910):

Oh sry, just saw "degrees" So you need to multiply by 180/pi to get 0.321750554*(180/pi) = 18.4349 which rounds to 18 degrees
