write a word problem about a real-world situation that would require you to subtract integers and have an answer of -6.

take weather

Step-by-step explanation:

the weather yesterday was -9 degrees

today thd weather has increased by 3 degrees

-9+3=-6 it's -6 degrees today

< 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
