The sum of all four interior angles in a quadrilateral must be 360, so the answer would be:
360 - 54 - 25 - 99 = 182
It is: 360-80-120-65 = 95 degrees which is the 4th angle
90 degrees
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 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.
360
In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle? 60° 90° 40° 20°
50 degrees (360 degrees in a quadrilateral)
125°
160 degrees
4
It is: 47 degrees
It is 360 degrees minus the sum of the other three angles.
Subtract the (sum of the other three angles) from 360.
The 4th angle is: 360-90-145-78 = 47 degrees
80 degree
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
