rise/run = tangent 15 degrees
rise = tan(15) x 48 = 12.86 inches

Anything less than 90 degrees. Over 90 degrees is an obtuse angle and anything under 90 degrees is an acute angle.
anything over 90o and under 180o.
I don't think you can. You can construct a 60º angle by compasses, but 65º sounds like a "Trisect" problem which (despite many claims to the contrary over many years) is not mathematically possible.
Nothing can be over 360 degrees. The angle 2000 degrees is not real as it cannot be drawn nor expressed.
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
No that is a right angle. An obtuse angle is any angle over 90 degrees.

An angle that is 136 degrees would be an obtuse angle. This is because its degrees are over 90 which is a right angle.
Anything less than 90 degrees. Over 90 degrees is an obtuse angle and anything under 90 degrees is an acute angle.
anything over 90o and under 180o.
An obtuse angle. There cannot be an angle with more than 180 degrees so it starts to count backwards when it hits 180. So instead of having a 190 degree angle, you have a 170 degree angle.
The rise over the distance is equal to the tangent of the angle Since tan (1 degree) = .0174 then the rise is .0174x13 = 0.227 meters ( 227 mm)
I don't think you can. You can construct a 60º angle by compasses, but 65º sounds like a "Trisect" problem which (despite many claims to the contrary over many years) is not mathematically possible.
An airplane over the Pacific sights an atoll at a 23 degree angle of depression. If the plane is 445m above water, how many kilometers is it from 445m above the atoll?
Obtuse Angle That would be an obtuse angle as the degrees are over 90, but less than 180.
3 degrees as in an angle? Yes, this is identified as an acute angle. Any angle under 90 degrees is an acute angle, a 90 degree angle is a right angle, and any angle over 90 is obtuse.
