Answer:
see explanation
Explanation:
the inscribed angle ADB is half the arc that subtends it , AB , then
AB = 2 × ∠ ADB = 2 × 46° = 92°
the central angle BOC is equal to the arc that subtends it, BC , so
BC = 22°
Then
ABC = AB + BC = 92° + 22° = 114°
-----------------------------------------------------
BD is a diameter of the circle , so BAD = 180° THEN
AD = 180° - AB = 180° - 92° = 88°
-----------------------------------------------------
the sum of the arcs on a circle = 360° , so
ADC = 360° - ABC = 360° - 114° = 246°
