HELP HELP PLEASE

B. 63

Step-by-step explanation:

We add up 13 + 13 first = 26

We add up all the 9 + 8 = 17

We add up the 6 + 4  = 10

We add up the 5 + 5 = 10

We add up totals starting with 10's backwards 37 + 26 = 63

(P):63

Answer is 63 or B

Step-by-step explanation:

< 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
