125°
50 degrees (360 degrees in a quadrilateral)
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.
if a quadrilateral has three right angles will also have have a fourth right angle. Making it a rectangle. The addition of all the angles in a triangle is 360 degrees. If there are three right angles, and you subtract their addition by 360, you will get ninty degrees.
For any quadrilateral (i.e. 4-sided figure), the angles will add up to 360 degrees. Since an obtuse angle is any angle with a measurement over 90 degrees, it is possible to have a quadrilateral with 3 obtuse angles. The fourth angle, however, must be acute (i.e. smaller than 90 degrees). Having 3 obtuse angles is not a requirement, however, for a quadrilateral.

4
It is: 47 degrees
80 degree
160 degrees
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.
