BRANLIEST IF CORRECT

2, 49, 63

Step-by-step explanation:

multiply x by 7 to get y

1) 2

3) 49

4) 63

Step-by-step explanation:

basically, you just have to figure out the difference between the input and the output. So input 4, output 28, I would guess that the proportion is 7, because 4 x 7 = 28. So for #1, do 14/7 to get 2. and so on. See the answer above.

< 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
