An obtuse angle is one over 90 degrees. If you are looking for the supplement it means that both angles have to equal 180 degrees. So the supplement of an obtuse angle would be an acute angle.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 149 degree angle is equal to 180 - 149 = 31 degrees.
A supplementary angle is that which, when added to the first angle, is equal to 180°.Therefore, we know that:162 + Supplement = 180Subtract 162 from both sides, and we can see that our supplementary angle is 18°.
A supplement to an angle in Geometry is a second angle with a size equal to the difference between 180 degrees and the size of the first angle. If the size of two angles is 180 degrees, then the angles are 'supplementary".
The angle is 105, its supplement is 75.
