1. in the above figure, ae = 2, ce = 3, and de = 4. what is the length of be? a. 6 b. 8 c. 5 d. 12

The answer that you are looking for is A.6. <

Hope this helps..

< 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
