The 110° angle  will subtend a major arc of  twice its measure  = 220°

So...the remaining minor arc subtended by its endpoints = 360 -  220  = 140° 

 

The  105° angle will subtend a major arc of twice its measure = 210°

So...the remaining minor arc subtended by its endpoints  = 360 - 210  = 150°

 

So....the major arc intercepted by  the enpoints of  α  =  150 + 140  = 290°

 

And its measure is  1/2  of this   =  1/2 * 290   = 145°
