In order to form a triangle then the sum of its angles has to be equal to 180 degrees. In order to find out if it’s possible to form a triangle from a specific set of angles, then you have to add them up and see if they are equal to 180 degrees. If they are then it’s a triangle if they less than or greater than 180 then a triangle cannot he formed.
Ok so let me help you with this. Here is the procedure: <span>r² = x² + y² = 8² + 6² = 100 r = 10 x = r cosθ y = r sinθ sinθ = y/r = 6/10 = 3/5 </span>Hope this is what you are looking for
