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.

To find a complementary angle, subtract the given angle from 90 degrees, since two angles are complementary if their sum equals 90 degrees. For example, if you have an angle of 30 degrees, its complementary angle would be 90 - 30 = 60 degrees. This method applies to any angle less than 90 degrees.
A complementary angle is one that, when added to a given angle, equals 90 degrees. Therefore, to find the complementary angle to a 31-degree angle, you subtract 31 from 90. This means the complementary angle measures 59 degrees (90 - 31 = 59).
If it's a triangle then: 180-sum of known angles = unknown angle
Of what?
The answer will depend on what the shape is!

The methods are subtraction. -- Subtract an angle from 90° to find its complementary angle. -- Subtract an angle from 180° to find its supplementary angle.
Complementary angles add up to 90*, so a 60* angle's complement is 30*.
Angles are complementary if they summate to the measure of a right angle (90 degrees). 90 - .01 = 89.99
Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.

It depends on what measure is missing.
