Its other 3 angles are 37 degrees, 143 degrees and 143 degrees

The law of any parallelogram says that the angle of one corner is the same as the angle opposite. So the other angles would also be 40 degrees and 140 degrees. Also note that this neatly adds up to a total of 360 degrees - all 4 sided shapes' angles must add up to 360 degrees, so you can work out the angles of a parallelogram just from knowing one angle.

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

Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.

What is the first angle

A parallelogram, in general, has no right angles.

If it's a parallelogram then the other 3 angles are 75, 105 and 105 degrees

Not too sure of your question but if one angle measures 115 degrees then the other 3 angles are 115 degrees, 65 degrees and 65 degrees because opposite angles are equal.

No. For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees. A parallelogram can be inscribed in a circle if it is a rectangle.

In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).

The opposite angle is the same as the known angle. Each of the adjacent angles is the supplementary angle to the known angle. That is the pair add up to 180 degrees.
