If answer is correct I will mark as brainliest The second step in the process for factoring the trinomial x^2-3x-40 is to:

A. list all the factors of 3

B. list all the factors of 40

C. find the sum of the factors of 40

D. find the sum of the factors of 3

correct

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
