An invisible angle!
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
A rectangle is not an angle (of any kind). It is a kind of quadrilateral.A rectangle is not an angle (of any kind). It is a kind of quadrilateral.A rectangle is not an angle (of any kind). It is a kind of quadrilateral.A rectangle is not an angle (of any kind). It is a kind of quadrilateral.
Then angle x is between 180 and 360 degrees
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.
a acute angle
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
That will depend on the size of the original angle of and what kind of shape it is which has not been given.

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.
a acute angle
It is a right angle.
Obtuse 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.
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
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.
