Question 595338: If I have a triangle, and one side is 35 degrees, and the other side is 28 degrees, how do I figure out the last side? I know you have to add them together and then you have to subtract, but I don't know what you subtract by.

You can put this solution on YOUR website! If I have a triangle, and one side is 35 degrees, and the other side is 28 degrees, how do I figure out the last side? I know you have to add them together and then you have to subtract, but I don't know what you subtract by.
---------------
Sides are units of length, not degrees. Unless you mean a spherical triangle, which I doubt.
----------
Assuming you mean the angles, the sum is always 180 degs.
35 + 28 = 63 degs
The 3rd angle is 180 - 63 degs
