Which statement is true

the system has no solution

Step-by-step explanation: for a solution to occur the lines have to cross

< 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

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
