In a triangle, the sum of all three angles is always 180 degrees.
Therefore, to find the measure of the final angle, we can subtract the measures of the first two angles from 180 degrees:
180 - 636363 - 696969 = -133152
Since we cannot have a negative angle measure, it is incorrect to state that the final angle measure is -133152 degrees. Instead, it indicates that there is a mistake in the measurements provided.
