I need help with this 293 ÷ 102
the answers are:
2.93
29.3
293
2,930

2.93

Step-by-step explanation:

The answer is appx. 2.8725, when rounded up it becomes 2.93.

< 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
