Given: Circle ABС45ADArc BC is a (either major or minor)arc. mBC = (either 45, 135, or 315)Arc BDC is a (either major or minor)arc. mBDC = (either 45, 135, or 315)

we have that
step 1
Arc BC is a minor arc
Find the measure of arc BC
arc BC=45 degrees ------> by a central angle
step 2
arc BDC is a major arc
Find the measure or arc BDC
arc BDC=360-45=315 degrees
