An adult short-eared owl weighed 1/2 pound. A baby short-eared owl weighed 2/9 pound. What was the total weight of the two owls?

13/18

Step-by-step explanation:

1/2+2/9 is 13/18

< 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
