NOTE :- GIVEN QUESTION IS INCORRECT.

CORRECT QUESTION :-

The measure of angles of triangle are in A.P. The smallest angle is 40. Find the angles of the triangle in degree and in radian.

• Smallest angle = 40°
• let 2 other angle be = 40+d and 40 + 2d

NOW,

→ 40+ 40+d + 40 + 2d = 180

→ 120 + 3d = 180

→ 3d = 180 - 120

→ 3d = 60

→ d = 60/2

→ d = 20°

THEREFORE,

• Smallest angle = 40°
• other angle = 40+d = 40+20 = 60°
• larger angle = 40 + 2d = 40+2×20 = 80°
