I WILL GIVE BREAINLIEST 1. 4x+3y=15
2 3x-4y=-8
3. y + 1 = 4/3 (x-6)
4. y= 3/4 x - 5

which pair of lines are linear?

a. 3 and 4
b. 1 and 2
c. 1 and 3
d. 2 and 4​

< 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
