Step-by-step explanation:

Sum of Angles in a Triangle = 180°

(2x + 30°) + (3x + 40°) + (5x + 50°) = 180°

10x + 120° = 180°

10x = 60°

x = 6°

Angle 1 = (2x + 30°) = (2×6° + 30°) = (12° + 30°) = 42°

Angle 2 = (3x + 40°) = (3×6° + 40°) = (18° + 40°) = 58°

Angle 3 = (5x + 50°) = (5×6° + 50°) = (30° + 50°) = 80°

The three angles of Triangle are 42°, 58°, 80°

The value of x is 6°
