1) Draw a circle of radius 32 2) Draw a radius (meeting the perimeter at A) 3) Based on the radius, construct an angle at the centre of the circle of 100° - draw a second radius (meeting the perimeter at B) 4) Based on the second radius, construct an angle at the centre of the circle of 120° - draw a third radius (meeting the perimeter at C) Note : the angle between the third and first radii measures 140°. 5) Draw chords joining A to B, B to C, and C to A. The triangle ABC has angles measuring 50°, 60° and 70°. NOTE : The process is based on the Theorem that the angle subtended by an arc at the centre of a circle is twice the angle subtended at any point on the circumference.

It's a 50 degree angle. It's an angle that measures 50 degrees. It's the complementary angle of a 40 degree angle.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.

the cotangent of a 50 degree angle is -3.678 This is in Radians. The cotangent of a 50 degree angle is .8391 (rounded) degrees.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.

The angle of reflection would be 50 degrees as well, following the law of reflection which states that the angle of incidence is equal to the angle of reflection.
