95 degrees, because 80+110+75=265 and the total degrees a quadrilateral should have(360) minus 265=95
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
It is: 360-80-120-65 = 95 degrees which is the 4th angle
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
Since a quadrilateral can mean any 4-sided shape there is no true definition of their angles. A square is always a quadrilateral and therefore it's angles will always equal 90 degrees. 6-2(180)=360 360/4= 90
The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
50 degrees (360 degrees in a quadrilateral)
4
It is: 47 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?
80 degree
The 4th angle is: 360-90-145-78 = 47 degrees
The 4 interior angles of any quadrilateral always add up to 360 degrees
The 4 interior angles of any quadrilateral add up to 360 degrees
125°
160 degrees
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
A vertex of a quadrilateral can have any measure between (but excluding) 0 degrees and 360 degrees. The only requirement is that the four angles add to 360 degrees. So a quadrilateral can have angles of 0.1, 0.1, 0.1 and 359.7 degrees.
