10

Step-by-step explanation:

Absolute value is positive since it’s the distance between the number and 0 on the number line.

|3|+|2|+|-5|=3+2+5 = 10

< 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
