A table is made using the following two patterns. Pattern x: Starting number: 9, Rule: add 3 Pattern y: Starting number: 3, Rule: add 1 real answers please!!!

answer: t=3

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
