An angle that is 129 degrees would be called an "obtuse" angle. This is because its measurements exceed 90 degrees but do not pass 180 which would be a straight line. Anything below 90 would be considered an "acute" angle.

The supplement of a 51° angle is 129° since the sum of the angles that form the supplementary angles is 180°.

An angle that is 129 degrees would be called an "obtuse" angle. This is because its measurements exceed 90 degrees but do not pass 180 which would be a straight line. Anything below 90 would be considered an "acute" angle.

A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 129 degree angle is equal to 180 - 129 = 51 degrees.

Obtuse. Any angle measuring greater than 90 degrees but less than 180 is considered obtuse. An acute angle is any angle measuring between 0 and 90 degrees. A right angle is an angle measuring exactly 90 degrees while a straight angle measures exactly 180 degrees.

Suppose the angle is x then its supplement is 180 - x so 180 - x = x - 78 that is, 258 = 2x or x = 258/2 = 129 <><><><><> Angle + Supplement = 180 Angle = Supplement + 78 Solve for the system of equations... Angle + Supplement = 180 Angle - Supplement = 78 ------------------------------------- 2 Angle = 258 Angle = 129 Supplement = 51

acute

The supplement of a 51° angle is 129° since the sum of the angles that form the supplementary angles is 180°.
