50 degrees (360 degrees in a quadrilateral)
125°
Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°
The interior angles of a quadrilateral always add up to 360 degrees. Therefore, 68+51+116=235 360-235=125 degrees.
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
The sum of the interior angles of a quadrilateral must equal 360 degrees. If you know three of the angles, just subtract them from 360 to find the fourth angle. In this case: 360 - 106 - 47 - 133 = 74
In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle? 60° 90° 40° 20°

125°
160 degrees
It is 360 degrees minus the sum of the other three angles.
Subtract the (sum of the other three angles) from 360.
It is: 47 degrees
4
The 4th angle is: 360-90-145-78 = 47 degrees
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
