Question

The angles of a a quadrilateral are in A.P. The greatest angle is double the least. Find all the four angles.

Answer 1

Since all angles are in Ap Let the four angles be a,a+x,a+2x,a+3x According to the question, 4×a=a+3x 3a=3x a=x Therefore the four angles become a,2a,3a,4a A/q,10a=360 a=36 2a=72 3a=108 4a=144
