11 in 2nd and 3rd and 12 question
in 11(ii). we hve to construct a line parallel to ab and cd and apply co interior property two times.. answer will be 36°
in 11(iii) we have to extend SR so that it cuts AB and apply alternate and corresponding angle property... answee will be 62
in 12(i) answer is 150
in 12 (ii) 3x+5x-20=180. solve it and u will get x=25
in 12(iii) 7x+4x+14+89=180 solve it and u will get x=7
