circle geometry

[shrewd salmon]

what are you solving for in this one?

[wild timber]

whats angle dac

oh

ok

if O is the center of the circle then OC is a radius, and thus andgle OCD should equal to when a line bisects a side of a cirlce

and then u can solved for angle ADB

solving for angle EBA should also be easy

then finding DAC shoudnt be that hard

But also isn't there a rule where angle abc should be right angle

Idk if that helps

And also angle adc is right angle

Yeah that helps
