-9

-4

|1|

|-2|

|-3|

|-5|

|-6|

Explanation:

When there is |#| around a number, it means the absolute value, and the absolute value is always positive.  So technically speaking, it would look like this -9, -4, 1, 2, 3, 5, 6; because the absolute value only means it has the value of whatever number which is in the |#|.

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
