You can calculate this on any scientific calculator. Those calculators don't usually have a special key for the cotangens, but this is the same as 1 / tan(68).
The third angle is 68 degrees which makes it a scalene triangle
Any two angles whose sum is equal to 90 degrees are called "complementary angles".

The trig identaty of cot(x) is cos(x)/sin(x) so then if we want to evaluate cot (68) deg. we just plug into the identady. so cos(68)/sin(68)=.404
90-22-68
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
The measured supplement of a 112-degree angle is found by subtracting it from 180 degrees. Therefore, the supplement is 180 - 112 = 68 degrees. This means that a 68-degree angle, when added to a 112-degree angle, equals 180 degrees, making them supplementary.
Any two angles whose sum is equal to 90 degrees are called "complementary angles".
An angle of 68 degrees is an acute 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).
The 3rd angle is: 180-35-68 = 77 degrees
