stmt 1. --> <cod + <cob + <boa = 180 (supplementary <s)
--> <cob + <boa= 120
<cob = 180 - 2*<obc (<s of a triangle)
--> <obc = 2*<bao (exterior < is twice of opp internal angles
also <bao = <boa (ab = oc = ob , ob = oc = radius)
<cob = 180 - 4<bao -- subsitute in eqn above and u will get <bao
stmt 2 <bco = 40 = <cbo (ob = oc = radius --> isoscles traiangle)
<obc = <obc = 2*<bao (exterior < is twice of opp internal angles
u will get <bao
ans D
my approach to use stmt 1 is bit lenghty...any shorter method??
