1- Name the Circle

3- Name Two Chords

5- Name a tangent

Name: Circle A

Chords: Chord DP, Chord HC

Tangent: EFG

Step-by-step explanation:

Name a circle by the center, in this case it's A.

Chord: A chord is a line only in the circle, not outside of it, and its endpoints are right on the circle.

Tangent of a circle: "Tangent" means touching, and this is a line, in terms of a circle, that touches the circle but is not INSIDE of the circle.  

< 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
