Help its a test and idk what to do

a: 1.26

b: 8190

Step-by-step explanation:

The account had a 26% increase. Therefore, you would multiply the original amount by 1.26.

1.26 x 6500 = 8190

< 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
