a. 2x+12=24

b. -7×20=118

c. 17+ 1/2x =10

d. -3+4x=-59

e. -3- 1/3x = -5

don't know sorry bru

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
