measure of arc AC

The arc AE is $42^\circ$. The arc AD is $90^\circ$. The arc DC is $90^\circ$. Thus, arc AC = arc AD + arc DC = $90^\circ + 90^\circ = 180^\circ$. This is incorrect. The arc AC is not a semicircle. The arc AD is $90^\circ$. The arc DE is $42^\circ$. The arc EB is $90^\circ$. The total angle of a circle is $360^\circ$. Arc AB is $90^\circ$. Arc BC is $90^\circ$. Arc AC is the arc from A to C. The arc ADC is $90^\circ + 90^\circ = 180^\circ$. This is a semicircle. The arc AEC is $90^\circ + 42^\circ + 90^\circ = 222^\circ$. The arc AC is not a semicircle. The question asks for the measure of arc AC. Arc AD is $90^\circ$. Arc DE is $42^\circ$. Arc EB is $90^\circ$. Arc AB is $90^\circ$. Arc BC is $90^\circ$. The arc AC is composed of arc AB and arc BC.
