Plz asap and do part 1 and 2 and plz plz show your work bc i am just confused

To find the polynomial that represents the area, multiply the two given side lengths and simply out using the FOIL method. Then substitute 5 in for x to solve part two.

< 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
