Answer :
Sum of angles of a triangle : 180°
So, 2x + x + 40 + x = 180
4x + 40 = 180
4x = 180 - 40
4x = 140
x = 35°
So, angles -
x = 35°
2x = 2×35° = 70°
x + 40 = 35°+40° = 75°
So, largest angle - 75°
So, 2x + x + 40 + x = 180
4x + 40 = 180
4x = 180 - 40
4x = 140
x = 35°
So, angles -
x = 35°
2x = 2×35° = 70°
x + 40 = 35°+40° = 75°
So, largest angle - 75°
