-2.7f + 0.8f -14 -5 please help

3.5f − 19

Explanation:

2.7f + 0.8f − 14 − 5

= 2.7f + 0.8f + −14 + −5

[ Combine Like Terms ]

= 2.7f + 0.8f + −14 + −5

= (2.7f + 0.8f) + (−14 + −5)

= 3.5f + −19

< 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
