Answer:

1 ) 180 - 71 = 109

2) 5x +x = 180 ;  6x = 180 ; x = 180/6 = 30

3) 90

4) x + 6x+8 + x+12 =  180 ;  8x + 20 = 180 ;  8x = 160/8= 30

5)  180 -110 = 70

6) m = 180- 119 = 61

7) 90

8) 11y - 36 = 63 ;  y = 99/11 = 9

~~~~~~~~Next page~~~~~~~~~~

(Q7) 180

(Q8) 2x+x = 3x = 90 ;  x = 90/3 = 30

(Q15) 157

(Q16) 5x + 4 + (x-2) + (3x+7) = 180

       9x +9 = 180 ;   x = 171 / 9 = 19

I hope im right!!
