Step-by-step explanation:
sum of all exterior angles = 360°
ACQ:
(2x + 20°) + (x+10°) + (3x+30°) = 360°
=> 2x + 20° + x + 10° + 3x + 30° = 360°
=> 2x + x + 3x +20°+10°+30° = 360°
=> 6x + 60° = 360°
=> 6x = (360-60)°
=> 6x = 300°
=> x = (300/6)°
=> x = 50°
=> 2x + 20° = 2(50)° +20° = 100°+20° = 120°
=> x + 10° = 50°+10° = 60°
=> 3x + 30° = 3(50°) + 30° = 150°+30°
= 180°
