A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
89.999... degrees. An acute angle is any degree under 90.
Suppose the angle is x degrees. Its complement is 90-x So x is 2/3 of (90-x) 3x = 2*(90-x) = 180 - 2x 5x = 180 so that x = 36 degrees
As many as you like because any triangle that has a 90 degree angle is always a right angle triangle.

A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
170 degrees.
89.999... degrees. An acute angle is any degree under 90.
Did you mean "degree"? There are 90 degrees in a right angle.
132
90 degrees.
An obtuse angle is a measurement of 91 degrees to 179 degrees. If it is 90 degrees, it is a right angle. If it is 1 degree to 89 degrees it is an acute. If it is 180 degrees it is a straight angle.
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
