How much does a obtuse in math add up to?

An obtuse angle in mathematics is defined as an angle that measures more than 90 degrees but less than 180 degrees. Therefore, the sum of an obtuse angle and a complementary angle (which would be an acute angle) can vary, but the obtuse angle itself does not have a specific sum. In a triangle, the sum of all interior angles is always 180 degrees, meaning an obtuse angle must be combined with two acute angles to maintain this total.
