What is the measurement of the fourth angle of a quadrilateral if the others measure 60 120 and 90?

The sum of the angles in a quadrilateral is always 360 degrees. Given the three angles measuring 60, 120, and 90 degrees, their sum is 60 + 120 + 90 = 270 degrees. To find the fourth angle, subtract this sum from 360 degrees: 360 - 270 = 90 degrees. Therefore, the measurement of the fourth angle is 90 degrees.
