The answer will depend on what the shape is!

If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.
It depends on what information is available.
180 minus two known angles = unknown angle
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
Subtract the two known angles from 180 degrees will give you the missing angle
the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
Of what?
That's how its meant to

To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
you cant
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
