Best Answer

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.

124 degrees

Polygons (regular, complex, irregular, etc) comes in many shapes, with a variety of interior angle totals. So the polygon in question needs to be more specifically named.

The angles are all 90 degrees in a square.

Are you talking about a triangle? If so, 33

If it's a triangle then: 180-sum of known angles = unknown angle

The answer depends on the context. Angles are related in many ways: parallel lines, angles at a point, angles in a polygon - all impose constraints on angles from which their measure may be determined.

If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
