Alternate Angle
That would be an obtuse angle measuring 150 degrees. I do not know of a proper name for it.
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
If angle A is congruent to angle B, then angle B is congruent to angle A.If X is congruent to Y then Y is congruent to X.
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)
Alternate Angle
Supplementary angle
Corresponding Angle
Y is a supplementary angle to angle X if X + Y = 180 degrees. The only opposite to X + Y = 180 is X + Y ≠180. Such an angle has no specific name.
supplementary angles on parallel lines.

I'm tempted to call it morbidly obese, but the proper name is "reflex angle."
Then angle x is between 180 and 360 degrees
for a book cover is this good
Suppose the angle is x degrees. Then supplementary angle = 180 - x and compementary = 90 - x So, 180 - x = 4*(90 - x) ie 180 - x = 360 - 4x or 3x = 180 or x = 60 degrees.
x and y are complementary so x + y = 90 and so y = 90 - x z and q are complementary so z + q = 90 and so q = 90 - z x = z so 90 - x = 90 - z that is y = q
Let's denote the measure of the angle as x degrees. The complementary angle would then be 90 - x degrees. According to the given information, we have the equation x = 14(90 - x). Solving this equation, we find x = 70 degrees and the complementary angle is 20 degrees.
