You cannot.
use the inverse sine or cosine or tangent
The 3 interior angles of any triangle add up to 180 degrees
When each of the 3 interior angles measure less than 90 degrees and the 3 sides are of different lengths
no because the algorithum states it mst be a triangle for the algorithem to work

All interior angles of a triangle MUST (a triangle by definition states that all interior angles MUST) add up to 180. Any measures would work, provided the three angles would add up to 180*....so a triangle with angles 1, 1, and 178 degrees works, as well as a triangle with 60, 60, and 60 degrees. Any angle combinations work, as long as the three angles add up to 180.

A triangle has no sum. There can be a sum of the measures of two or more angles, or the lengths of two or more sides, for example.
A triangle does not have any particular value. There are the magnitudes of its size, its angles, its area, its perimeter etc, but no single VALUE.
Using the trigonometrical cosine formula for a triangle the angles work out as 28.91 degrees 31.99 degrees and 119.10 degrees which add up to 180 degrees.
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
YesAnother Answer:-Yes under certain conditions depending on what type of triangle it is and the measure of the angle givenBut normally two angles are needed to find the third angle in a triangle
