How do you find a missing angle for a triangle?
Subtract the two known angles from 180 degrees will give you the missing angle
How do you determine the measurement of a missing angle in a angle?
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.
How do find an missing angle if theres one number?
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
How do you find a missing angle of a polygon?
That will depend on how many sides the polygon has.
You are trying to work out missing angles about certain points of angles in a triangle?
to find missing angles you are dealing with complementry and suplementry angles. Suplementry angles add up to 180 degrees so you must subtract what given angle you have from 180 and you come up with youre missing angle. This rule also gos for complementry but the angles must add up to 90 degrees
