Angles 1 and 2 are supplementary. Which equation represents the relationship between their
measures?
m21+ m22 = 90°
m21 + m22 = 100°
mZ1 + m 22 = 180°
m21+ m 22 = 2009

this ain't the right answer.. can you tell me the answer

angle 1 + angle 2 = 180 degrees

Step-by-step explanation:

supplementary angles add up to 180

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
