Subtract the two known angles from 180 degrees will give you the missing 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.
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
That will depend on how many sides the polygon has.
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
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
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. :)
If you have at least 2 of the angle measurements and are trying to find the measurement of a missing angle you should do this: When you have the measurement of two angles, add them together. Then subtract the total from 180(always the sum of all of the triangle's angle's measurements). It will give you the measurement of the missing angle. If you are trying to find the length of the missing side, then use the Pythagorean theorem (a squared+b squared=c squared, c being the missing side) THIS ONLY WORKS FOR RIGHT TRIANGLES, however. first of all this didnt help me. second that therom is stupid cuz im only in 8th grade integrated algebra! get me a good answer jeez. i need to find the missing lenngth help me someone ---------------------------------------------------------------------- Honey, the thereom is the only way to get the right answer. And I'm in 7th grade, so get over the "you're only in 8th grade" I'm in 7th grade and understood what he said. I'd suggest using the answer he gave, 'cause that's the best you can get.
Of what?
That's how its meant to
The answer will depend on what the shape is!

you cant
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
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.
