Which relationship between x and y in the equation shows a proportional relationship?

a: y + 5 = x + 3

b: y = 5 (x + 3)

c: y= 5x + 3

d: y=3x

you guys are smarter than me,

D: y=3x

Step-by-step explanation:

I hope this helps! :D

< 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
