HARD CIRCLE GEOMETRY QUESTIONS

A Hard Geometry Problem on circle - Stack Exchange
A Hard Geometry Problem on circle. do i find $\angle(ODC)$? so i wanted to show my teacher this but his not available yet. Can someone help me to solve? geometry problems which on circle seems hard to me. Thanks! geometry circles. share | cite Browse other questions tagged geometry circles or ask your own question. asked. 2 years, 1Without loss of generality, we can consider $R=OC=OB=1$. From $\Delta OBC: \frac{OB}{\sin20}=\frac{BC}{\sin140}\Rightarrow BC=\frac{\sin140}{\sin20..Best answer · 3Join OA and AC angle AOC = 2xangle ABC=60 deg (center angle and circumference angle) OC=OA (radii) Triangle OAC is equilateral AC=OA=OC angle CAB =..3Hint. a bit of angle-chasing you should be able to establish$\angle ADC=70$. You can then use the sine rule in triangles$ODB$and$ODC$(as..0$$/angle(ABC)=30°// /angle(AOC)=2*angle(ABC)=60°//$$ So AOC is equilateral triangle (AO=AC=CO=R) $$/angle(CAB)=/angle(COB)/2=70° //angle(ACD)=70°$$..0Produce CD and meet the circle at E Join OA and AC angle APC = 60 deg (centre and circumference angles) OA = AC = OC Join BE angle CAB = angle CEB..0BCD is equal to 40 (OCD plus BCO). So the unknown corner of the triangle is 180 - (40 + 30) which is 110. ADC, CDB and ODB are supplementary, so AD..First join$AC$and$AO$. Now,$\angle ABC$is$30^\circ\$,so AOC is 60*=OC,OAC=OCA=(180*-60*)÷2=60*. Triangle AOC is equilateral Triangle,..
