It is a reflex angle which is greater than 180 degrees
105 degrees

In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
The 4 interior angles of a parallelogram add up to 360 degrees
It is a reflex angle which is greater than 180 degrees
The angles are, 20°, 50°, and 110°.
When doing these types of problems, start with the fact that the sum of the angles in any triangle is 180 degrees (Any planar triangle that is.)So let the smallest angle be x. The largest angle is x+100 since we are told the largest angle is 100 degrees larger than the smallest angle.Now the third angle is x+5 by the same reasoning.So now we add x+x+5+x+100=1803x+105=1803x=75so x=25.The smallest angle is 25 degrees.The largest is 125 degrees and the third angle is 30 degree.Note that 125+25+30 is 180 as desired.
Sum of all the angles in the triangle has to be 180 degrees. Let's mark the largest angle as x. Then, smallest angle will be 0.5x and the middle one x-25. x + 0.5x +x - 25 = 180, which is after simplyfying: 2.5x = 205 x = 82 degrees -> the largest angle, x-25 = 57 degrees -> middle one, 0.5x = 41 degrees -> the smallest angle.

Not always because the largest angle of a right angle triangle is between its smallest sides which measures 90 degrees
105 degrees
A parallelogram, in general, has no right angles.

It is 1 degree after a right angle. A right angle is 90 degrees so the smallest obtuse angle is 91 degrees.
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
The answer is 360 degrees.
