A pair of supplementary angles total 180 degrees. In this instance, the supplement to a 65 degree angle would be 180 - 65 = 115 degrees.
It is an obtuse angle
it is a obtuse angle
Not too sure of your question but if one angle measures 115 degrees then the other 3 angles are 115 degrees, 65 degrees and 65 degrees because opposite angles are equal.
115 degrees
Obtuse
Yes. The fourth angle is 115 degrees.
Use a protractor.
A 115 degree angle is classified as obtuse. Scalene and isosceles refer to types of triangles.

It is an obtuse angle because it is greater than 90 but less than 180 degrees
A pair of supplementary angles total 180 degrees. In this instance, the supplement to a 65 degree angle would be 180 - 65 = 115 degrees.
32.5 degree each
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.)
180 degrees and 115 degrees
It is: 180-115 = 65 degrees
