Want this question answered?
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.

If it's a triangle then: 180-sum of known angles = unknown angle
1 plus 2 is equal to 3
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.
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.
Difference between two complementary angle is 60 degree find its angle
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
If it's a triangle then: 180-sum of known angles = unknown angle
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
90-20= 50 so50 is the complementary angle of 20
