After the egg from Team B flew through the air and landed down the field, the group of students tracking the path of the egg determined that the equation y = -x² + 23x – 42 represents the path the egg took through the air. Find
the vertex and use it to graph the equation

answer: i believe its b. if you sound out the sentences that sounds wrong.

< 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 answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
