The measure of the angles of a triangle are represented by (2x) °, (x+40) °, and (x) °. what is the measure of the largest angle of the triangle?

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°
