Aob is a diameter of a circle CD parallel to a b if angle b a d is equal to 30 then angle C is equal to how much
Angle ADB = 90*
Angle ABD = 60*
Angle CAD = 30*
Angle CDA = 30*
Therefore, Angle C = 180- (30+30) = 180-60 = 120*
Angle ABD = 60*
Angle CAD = 30*
Angle CDA = 30*
Therefore, Angle C = 180- (30+30) = 180-60 = 120*
