Step-by-step explanation:

\huge\color{orange}{\underline{\underline{Answer\::}}}

Total Angle of Triangle = 180°

[ Angle sum property of triangle]

 x°  + ( x - 20 °) +  ( x - 40° ) = 180°

 x + x -20 + x - 40 = 180 °

 3x - 60 = 180°

 3x  = 180 + 60

 x =  240/ 3

 x = 80°

Values of each angle

x° = 80°

x - 20 ° = 80 - 20

= 60°

x - 40° = 80 - 40

= 40°
