Obtuse angle
An angle measuring 109 degrees is classified as an obtuse angle. In geometry, an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. In this case, the angle of 109 degrees falls within this range, making it an obtuse angle.
To find the missing angle that, when added to 109 degrees, totals 180 degrees, you would subtract 109 from 180. This calculation gives you 180 - 109 = 71 degrees. Therefore, the missing angle is 71 degrees.
