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
Acute angle
90 - 68 ie 22 degrees
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".
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''
The sum of the three angles of a triangle will always be 180 degrees. So to find the third angle, one must take 180 - 35 - 77. The answer would be 68
