The variables y and x have a proportional relationship, and y = 15 when x = 3. What is the value of x when y = 4?

Helppp me please

I think 2

Step-by-step explanation:

y=15 and x=3 5x3=15 and 2x2=4

took the test it's 94

< 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
