What are the auxiliary formulae of the statement "sum of the angles of a quadrilateral ABCD is 360^(@) ," (The four angles of the quadrilateral are A,B,C and D)?

The sum of the four angles of a quadrilateral is 360^(@) . Three angles of a quadrilateral are respectively equal to 110^(@), 50^(@) and 40^(@) . Find its fourth angle.

Assertion (A) : If three angles of a quadrilateral are 130^@,70^@ and 60^@ then the fourth angle is 100^@ Reason(R) : The sum of all the angle of a quadrilateral is 360^@ The correct answer is : (a) /(b)/(c )/(d).

The sum of the four angles of a quadrilateral is 360^(@) . In a quadrilateral ABCD, the angles A, B, C and D are in the ratio 1:2: 4:5, then the measure of each angle of a quadrilateral is
