Oh, dude, a 68 degree angle is just called a 68 degree angle. Like, that's its name. It's not like a secret agent with a cool code name or anything. It's just chillin' there at 68 degrees, doin' its thing.
90 - 68 ie 22 degrees
The third angle is 68 degrees which makes it a scalene triangle
90-22-68
Any two angles whose sum is equal to 90 degrees are called "complementary angles".
An angle of 68 degrees is an acute angle
An angle greater than 90 degree is an obtuse angle.
Complement: 22 Supplement: 112
A 68-degree angle is classified as an acute angle, as acute angles are defined as being less than 90 degrees. This means it is sharper than a right angle but not as sharp as an angle that is less than 0 degrees.
The cotangent is the reciprocal of the tangent, so simply calculate, on your scientific calculator, 1 / tan(68).
