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''
I don't see an angle. Do you mean finding angles from a triangle? The three angles have to add up to 180 degrees. If it gives you (for example) 72 degrees and 68 degrees, what's the missing angle? Well, we add 72 and 68 up, then subtract it from 180. Our answer is found! Hope this helps, Conor
