125 degrees
360 minus the sum of the other three.
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
95 deg
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°
360 minus the sum of the other three.
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°
Yes. The fourth angle is 115 degrees.
It is 100 degrees.
Add up the three angles and subtract that from 360.
90 degrees
Subtract 300 from 360.
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.
