33
It is a right angle.
a acute angle
An obtuse angle
Complementary angles add up to 90°. The complementary angle of 33° is therefore 90 - 33 = 57°.
It is: 147 degrees because 147+33 = 180 degrees
327 degrees (or -33 deg).
That depends on how long it is. The thickness should be just about 0.65 x the length to make a 33 degree angle.
