To find the third angle of a triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the three angles in a triangle is always 180 degrees.
Given that one angle measures 25 degrees and the other angle measures 68 degrees, we can find the third angle by subtracting the sum of these two angles from 180.
Third angle = 180 - (25 + 68) = 180 - 93 = 87 degrees.
Therefore, the third angle of the triangle is 87 degrees.
