1.	In the given figure AB and AC are opposite rays.(i) If x- 27, find y.(ii) If y 25Â°, find x(5y + 21)Â°
Answer» I) Sum of angles on a line = 180.=> 5y+21+2x = 180=> 5y+21+2(27)=180=> 5y + 21+54= 180.=> 5y = 180-75=> 5y = 105.=> y = 21. ii)=> 5y+21+2x = 180=> 5(25)+21+2x = 180=> 146+2x = 180=> 2x = 34=> X = 17. Please hit the like button if this helped you. thank you!

Answer»

I) Sum of angles on a line = 180.=> 5y+21+2x = 180=> 5y+21+2(27)=180=> 5y + 21+54= 180.=> 5y = 180-75=> 5y = 105.=> y = 21.

ii)=> 5y+21+2x = 180=> 5(25)+21+2x = 180=> 146+2x = 180=> 2x = 34=> X = 17.
