1.	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)?A. `A=360^(@)-(B+C+D)` `B=360^(@)-(A+C+D)` `C=360^(@)-(A+B+D)` `D=360^(@)-(A+B+C)`B. `A=360^(@)-(B+C+D)` `B=360^(@)-(A+C+D)` `C=360^(@)-(A+B+D)` `D=360^(@)-(A-B+C)`C. `A=360^(@)-(B+C+D)` `B=360^(@)-(A-C+D)` `C=360^(@)-(A+B+D)` `D=360^(@)-(A+B+C)`D. `A=360^(@)-(B+C+D)` `B=360^(@)-(A+C+D)` `C=360^(@)-(A-B+D)` `D=360^(@)-(A-B+C)`
Answer» Correct Answer - A `angleA+angleB+angleC=360^(@)`. Make of the angles as the subject. (ii) Given, `A+B+C+D=360^(@)`, make A,B,C and D as subjects.
