An acute angle
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
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
It does not; if there is no 90 degree angle there is no hypotenuse.
