Someone please help algebra 1 honors is so hardd

2^12 + 8^1/2 = 2^1/2 + (4 * 2)^1/2 = 2^1/2 + 2 * 2^1/2 = 3 * 2^1/2

Check:    3 * 2^1/2 = 4.24

2^1/2 + 8^1/2 = 1.414 + 2.828 = 4.24

< 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
