13.28

Step-by-step explanation:

Meaning, you must compare a number and the next one. So if you pick 3, you also compare 4.

And actually coincidentally, the answer IS, 3 and 4. If you take the -9.7 and the -22.98 and compare the difference, you get 13.28. That is the GREATEST difference between any other depth check there. So 13.28 is your answer.

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
