Hi please add those properly you will get 3x=180 then divide by 3 thus 60⁰. To prove your answer substitute back the value of x in the equation you must get 180. But if you substitute 30 that's not 180 . So 30 is the one which is incorrect.
Kindly please re-read the question with understanding...S3=x S2= 2x S1=3x then from there u calculate : x + 2x + 3x = 180 6x = 180 6x ÷ 6 = 180 ÷ 6 x = 30° U can rectify by substituting sir
Your in 2.2 is very wrong, x is suppose to be 30° not 60°
Your answer is wrong in 2.2
