Question

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

Answer 1

Answer:

60,80,100,120

Step-by-step explanation:

let the angles be a,a+d,a+2d,a+3d.

Given,

2a=a+3d

a=3d

a+a+d+a+2d+a+3d=360

18d=360

d=20

a=3×20=60

Hence angles are 60,80,100,120.
