80
The angles in a quadrilateral add up to 360 degrees.
So if 3 angles = 280 the fourth angle is 360-280 = 80

Is the sum of the measures of the angles of a quadrilateral equal to 180 degrees?
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
What is the sum of the measure of the angles of a quadrilateral?
360 degrees
What is the sum of the measure of the exterior angles of a quadrilateral?
The sum is two straight angles or 360 degrees.
Given two parallel lines with a transversal if one of the angles measures 50 degrees what are the measures of all the other angles?
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
What are supplementary angles that are NOT a linear pair?
Any two angles whose measures add up to 180 degrees. For example, opposite angles of a cyclic quadrilateral (quadrilateral whose vertices are on a circle).
If three angles of a quadrilateral are congruent and the average of the measures of two angles of the quadrilateral is 80 which number could NOT be the measure of an angle of the quadrilateral?
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
