If A quadrilateral has 3 angles 90 100 120 what is the fourth angle?

The sum of the four angles is 360 degrees. Three of the angles add up to 310 so the fourth must be 360 - 310 = 50 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)


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


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°


If three angles of a quadrilateral measure 80 degrees 120 degrees and 65 degrees what is the fourth angle?

It is: 360-80-120-65 = 95 degrees which is the 4th angle


What is the proof that the sum of the angles of a hexagon equals 720?

There are 6 angles in a hexagon, and each angle measures 120 degrees. 120 x 6, or 120+120+120+120+120+120=720.


If a trapezoid has a sixty degree angle a hundred twenty degree angle and an eighty degree angle what is the measurement of the fourth angle?

The sum of the angles in a trapezoid is 360 degrees, therefore, the forth angle in this problem is: 360 - (60+120+80) = 100 degrees


What is 120 as a percent of 100?

120 is 120% of 100.


How many interior angles in 120 sides?

120, if it is a polygon.


What is the supplement of a 120 degree angle?

Supplement angles = 180° So 180° - 120° = 60° Complementary angles = 90°


What is 12 over 120 as a percent?

100*12/120 = 10%100*12/120 = 10%100*12/120 = 10%100*12/120 = 10%
