In a triangle, the sum of two of the angles is equal to the third. if the lengths of the two longer sides are 12 and 13, what is the length of the shortest side?

The sum of two angles is equal to the third

The longer sides (longer and longest) is 12 and 13

13 - 12 = 1

this means that the length of the shortest side is 1 (for 1 + 12 = 13)

hope this helps
