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
160 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.Calculate the fourth angle so that the sum of the angles is 360 degrees.
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.
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 so if 3 of them are right angles (90 °) the remaining fourth angle must also be 90 °. 360° - 3x90° = 90°
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
50 degrees (360 degrees in a quadrilateral)
125°
160 degrees
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°
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
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.
80 degree
