The angles of a triangle are in A. P. and the number of degrees in the least angles is to the number of degrees in tha mean angle as
1 : 120. find tha angles in radians .
AshishRana:
there's no such thing as 'mean' angle. Post the correct question.

the angles are a-d,a,a+d.
so a-d+a+a+d=180 degree
3a=180 degreea=60 degree
given that a-d/a=1/120(60-d)/60=1/120120-2d=1d=119/2
so angles in radians will be 60-119/2=1/2 degree,60degree,60+119/2=239/2 degree in radians anlgles will be
pi/360,
pi/3,
239pi/360.
so a-d+a+a+d=180 degree
3a=180 degreea=60 degree

hmm thanks
