An angle of 109 degrees is an obtuse angle.
Obtuse angle
If they are the angles of a triangle then the missing angle is 116 degrees
If it's a right angle triangle then the the third angle is 60 degrees.
Thmissing angle is 83
An angle of 109 degrees is an obtuse angle.
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.

I will assume that this is referring to a triangle. The angles of a triangle add up to 180 degrees. Let the missing angle = a then a + 22 degrees + 51 degrees = 180 degrees a = 107 degrees
19 degrees and 109 degrees respectively
In a tetrahedral molecule the characteristic angle between atoms is 109,5 degrees.
