The supplement of an 80 degree angle is an 100 degree angle.
78 degree angle
a 10-degree angle
66 degree angle
15 degrees. A bisected 60 degree angle makes 2 30 degree angles by definition of an angle bisector, then a 30 degree angle makes 2 15 degree angles by definition of an angle bisector.
I want to say it is a 48 degree angle
acute
42 degrees
66
the maximum angle for staircase is 42 degree
90 - 42 ie 48 deg
69 degrees
Depends on what you mean by compliment. If its the compliment to a 90 degree angle it would be 42 degrees.
90/100
The 110 degree angle makes this triangle an obtuse triangle.
well you know what a right angle looks like? well its not half of that. however half of a right angle is 45 degrees so close to 42
You get two angles measuring 21 degrees!
