You can put this solution on YOUR website! If you have a 46 degree triangle and you know the lengths of 2 sides,
how do you determine the length of the third side.
:
Assuming you mean, side angle side situation, use the law of cosines
Where a is the unknown side, opposite the 46 degree angle, b & c are the known sides.
:
a^2 = b^2 + c^2 - 2bc*cos(46)
