    Well you have to start by testing each of the numbers times 2 then add them. 70 x 2 = 140 10 x 2 = 20 140 + 20 = 160....

    The sum of all the angles of a triangle need to be 180 degrees, so that means if two of the angles are already determined, the other angle can only be one specific number that makes the sum 180. So only 1 unique triangle can me made in this case. :P
