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

An angle of 68 degrees is an acute angle

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
Use the tangent ratio: tan = 22.5/34 = 45/68 tan-1(45/68) = 33.49518467 degrees Angle of elevation = 33o29'42.66''
20 degree Celsius = 68 degree Fahrenheit
