If the measures of three angles of a quadrilateral are , and then, find the measure of fourth angle.
Solution:
let the fourth angle =
x
   We know that sum of angles of a quadrilateral = 360
therefore ,
   
  100 + 84 +76 + x = 360
      260 + x = 360 
       x = 360 - 260
       x = 100

Therefore the fourth angle is .

Measure of angles of a quadrilateral =360○
=> 100+84+76+a=360○
=> a=100○
