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°
50 degrees (360 degrees in a quadrilateral)
125°
The fourth exterior angle is 93 degrees so the fourth interior angle must be 87 degrees because there are 180 degrees on a straight line.
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.
The interior angles of a quadrilateral always add up to 360 degrees. Therefore, 68+51+116=235 360-235=125 degrees.
If it is a 4 sided quadrilateral then the 4th measurement is 96 degrees
360 - (80 + 120 + 65) ie 95o
50 degrees (360 degrees in a quadrilateral)
It is: 47 degrees

110 degrees.
80 degree
95 deg
125°
160 degrees
The answer would be 90 degrees, because the quadrilateral's angles should add up to 360 degrees. 360 - (60 + 120 + 90)= 90 120 + 60 = 180 + 90 = 270 + 90 = 360
The sum of the internal angles of a quadrilateral is 360 degrees. Therefore given the three angles 60, 120, and 90, the fourth would be (360) - (60 + 120 + 90) = 360-270 = 90 degrees
