hi i need help on this one problem i’m not completely understanding what to do or what the answer is!!

Step-by-step explanation:

Starting at 0:8 for every time the x(or the 0) changes up by 1 the y(or the 8) goes down by one

do that with the other  but look how the 4:11/12 is diff form the others. This usually means thar is is a pattern so it should look like

3:10

4:11/12

5:13

6:14

7:15/16

8:17

26

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
