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.)
