It is an obtuse angle because it is greater than 90 but less than 180 degrees
Use a protractor.
A 115 degree angle is classified as obtuse. Scalene and isosceles refer to types of triangles.

an obtuse angle
An obtuse angle is an angle that measures between 90 and 180 degrees. A 115-degree angle falls within this range, specifically closer to 90 degrees than 180 degrees. Visually, an obtuse 115-degree angle would appear wider than a right angle (90 degrees) but not as wide as a straight angle (180 degrees). It would resemble an open arm, wider than a right angle but not forming a straight line.

A pair of supplementary angles total 180 degrees. In this instance, the supplement to a 65 degree angle would be 180 - 65 = 115 degrees.

115 degrees is an obtuse angle
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
