Х Gerardo is going to
create a kite to fly in
the park. He decides
to create the kite
using two isosceles
triangles. The pattern
he used to create his
kite is shown below.
Which equation can
Gerardo use to
determine the
amount of material
he will need to build
the kite?

he needs paper 2uuwujw8x38i2

step-by-step explanation:

< 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
