    tan(x) = (49.6/57.4) (opp/adj) x = tan^-1(49.6/57.4) That's the inverse tangent. There should be an option on your calculator for that.

    Does the teacher let you use calculators or did they mention a table you could use for looking up these values? B/c that's how they did it in the old days.

    40.83 degrees The reverse of a tangent is referred to as both the inverse tangent and the arc tangent. So on a calculator, it will either show up as tan^-1, atan, or arctan. You also want to make sure that you mode is in degrees, not radians. Talk with your teacher if you're still unsure b/c it's important :-)
