It is 360 degrees minus the sum of the other three angles.
Subtract the (sum of the other three angles) from 360.
If those are the angles of a quadrilateral then the 4th angle is 360-100-80-100 = 80 degrees
125 degrees
95 deg
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°
It is 100 degrees.
Yes. The fourth angle is 115 degrees.
Add up the three angles and subtract that from 360.
90 degrees
50 degrees (360 degrees in a quadrilateral)
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.
It is 360 degrees minus the sum of the other three angles.
Subtract the (sum of the other three angles) from 360.
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.
It is a right angle trapezoid
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°
