INSCRIBED ANGLES PLZ HELP ASAP
Taya2010 [7]
The answer is 46°.

The measure of an inscribed angle is equal to (1/2) the measure of the intercepted arc. 

That means that, since ADC is 23 degrees, doubling that gives you 46 degrees, the measure of the intercepted arc.

Central angles are equal to the measure of the intercepted arc, which in this case is the same arc we just calculated.

Therefore it's 46.
