Question

the angles of a quadrilateral are 90degree 60degree 110degree . what is the fourth angle?

Answer 1

sum of angles of a quadrilateral add upto 360 degrees so ATTQ

=> let the forth angle be x then

=> 90 + 60 + 110 + x = 360

=>260 + x = 360

=> x = 100

Answer 2

90 degree +60degree+110degree +fourth angle =360degree .....(sum of all angles in quadrilateral is 360degree)
260 degree +fourth angle =360degree
fourth angle =360degree-260degree
fourth angle =100degree
