To find the measurement of the fourth angle in a quadrilateral when three angles are given, you can use the property that the sum of all angles in a quadrilateral is always 360 degrees. Given that the three angles are 90, 145, and 78 degrees, you can add these together and subtract the sum from 360 to find the measurement of the fourth angle. Therefore, the fourth angle would be 360 - (90 + 145 + 78) = 47 degrees.

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.


What is the measurement of the fourth angle if a quadrilateral if the others measure 80 degrees 120 degrees and 65 degrees?

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°

An irregular quadrilateral has exterior angle measures of 93 85 and 89 what is the measure of the fourth interior angle?

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.


The sum of the measures of three angles in quadrilateral is 280 degrees What is the measure of the forth angle?

80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80


The measures of the three angles of a quadrilateral are 80 140 55 find the measure of the fourth angle?

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


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

The answer would be 90 degrees, because the quadrilateral's angles should add up to 360 degrees. 360 - (60 + 120 + 90)= 90 120 + 60 = 180 + 90 = 270 + 90 = 360


What is the measure of the forth angle of a quadrilateral if one angle measures 106 degrees and the other measures 47degrees and the third one measures 133?

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


What is the degrees of the angles in a quadrilateral?

The sum of the interior angles in a quadrilateral is always 360 degrees. This means that if you know the measures of three angles, you can find the fourth angle by subtracting the sum of those three angles from 360 degrees. Each individual angle can vary, but their total will always equal 360 degrees.


What is the measurement of the fourth angle of a quadrillateral if the outhers measure 60 degrees 120 degrees and 90 degrees?

The sum of the internal angles of a quadrilateral is 360 degrees. Therefore given the three angles 60, 120, and 90, the fourth would be (360) - (60 + 120 + 90) = 360-270 = 90 degrees


If three angles of a quadrilateral measure 90 100 and 120 what is the measure of the fourth angle?

50 degrees (360 degrees in a quadrilateral)
