i really dont know this problem i try to enter in but it wont actually tell me the answer
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
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 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.
It is: 360-80-120-65 = 95 degrees which is the 4th angle
90 degrees
If it is a 4 sided quadrilateral then the 4th measurement is 96 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°
360 - (80 + 120 + 65) ie 95o
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.
the angle measures of a quadrilateral must equal 360 degrees so you add 80+140+55=275 then subtract from 360. the answer is 85
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
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
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
50 degrees (360 degrees in a quadrilateral)
110 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.
