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°
