Find the missing values of each triangle given below. Round to the nearest tenth.

< 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

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

it would take 7/10 of an hour too fill the pool.
