It is: 47 degrees
80 degree
It is 360 degrees minus the sum of the other three angles.
The sum of the angles in a quadrilateral is always 360 degrees. Given the three angles measuring 60, 120, and 90 degrees, their sum is 60 + 120 + 90 = 270 degrees. To find the fourth angle, subtract this sum from 360 degrees: 360 - 270 = 90 degrees. Therefore, the measurement of the fourth angle is 90 degrees.
With quadrilaterals, if there are three equal angles, then we know that the fourth angle must be equal, so the quadrilateral is a rectangle. * * * * * That is absolute rubbish. You can have a quadrilateral with three angles of 70 degrees and the fourth of 150 degrees. There is no name for such quadrilaterals and the only thing that can be said about them is that they are irregular.
No, it is not possible to have a quadrilateral with three obtuse exterior angles. The sum of the exterior angles of any polygon is always 360 degrees. If three exterior angles are obtuse (greater than 90 degrees), their combined measure would exceed 270 degrees, leaving less than 90 degrees for the fourth angle, which must be acute. Thus, a quadrilateral cannot have three obtuse exterior angles.

It is 360 degrees minus the sum of the other three angles.
The 4th angle is: 360-90-145-78 = 47 degrees
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°
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.
4 sides requires Total interior angles of 360 degrees 360-90-90-91= 89
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.
