A triangle has sides a , b and c . Page a stands against the angle α . Page b stands against the angle β . Page c stands against the angle γ . Determine the angle α , if a=19 cm, w=21 cm and β=27∘ . Answer in degrees to two correctly rounded decimal places (remember to use decimal point). If there is no triangle that meets the conditions, answer with the empty set. Example. α={} If the conditions determine a unique triangle, answer with the angle α inside braces {} (solution set with one element). Example. α={48.12} (in this unique triangle case the braces can be omitted) If two different triangles meet the conditions, answer in the form {α1,α2} Example. α={48.12,131.88} The order of the angles does not matter. (NOTE! Commas separate the elements. Decimal points separate integer and decimal parts.)

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
