PLEASE ANSWER THIS WORKSHEET QUICK!

1. -14 x 9 = -126

2. -250/-50 = 5

3. -8 x -12 = 96

4. -72 / 9 = -8

5. -5 x -11 = 55

6. -140 / 20 = -7

7. -(12 x -12) = 144

8. 84 / -14 = -6

9. 15 x -7 x -1 =  105

10. (-288/16) / -3 | (-18) / -3 = 6

11. -(6 x -5 x 2) = 60

12. -(-216/-12) / -2 | -18 / -2 = 9

13. -13 x 2 x -3 = 78

14. -195 / -13 / 5 | 15 / 5 = 3

15. (-4 x -4) / 2 | 16 / 2 = 8

16. (-1 x -18 x -4) / (-3 x 2) | -72 / -6 = 12

17. (14 x -3) / -6 = 7

18. - ((15 x -12 x 3) / -45) | - (-540 / -45) = 12

19. (-5 x -6 x -3) / 9 = -10

20. (12 x 10 x -4) / (-5 x -3 x -1) | -480 / -15 = 32

Hope this helps!! :)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
