After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air Josephine says she can do this by using dans equation (h(t) = -16t^2 + 18t +8) and setting the equation to 0. Dan doesn’t Josephine is correct.

Explain your reasoning using mathematical evidence

< 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
