name 3 rays, name a pair of opposite rays with endpoint of c and name a pair of opposite rays with a different end point

Name 3 rays of this line ABC,DCB,CDA

Step-by-step explanation:

ABC

DAC

BC

there u go bud

< 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
