use the inverse sine or cosine or tangent
You use the counting numbers: 1, 2, 3, and so on.
3 angles- TRI(three) angles
No not never can a triangle have 3 obtuse angles but it can have 3 acute angles
Use a protractor and you'll find that the 3 interior angles add up to 180 degrees and that the 3 exterior angles add up to 360 degrees

you can use up to 2 angles in a supplementary angle. Just find 2 angles to fit into 180 degrees.

Angles of 3 degrees and 6 degrees are acute angles.
No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 angles.
It is an isosceles triangle having 3 interior angles 2 of which are equal in size and the 3 angles add up to 180 degrees. Use Pythagoras' theorem to find its altitude and then use trigonometry to find the sizes of its angles. The angles work out as 53 degrees, 53 degrees and 74 degrees
