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.

115 degrees is an obtuse angle
It is: 180-115 = 65 degrees
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.)
