Answer 1

Because angle COB = angle AOD
Therefore
$2x - 100 = x + 2 \\ 2x = x + 2 + 100 \\ 2x = x + 102 \\ 2x - x = 102 \\ x = 102$
Therefore angle COB=2x-100= 2×102-100=204-100=104
angle AOD=x+2=102+2=104.
Because angle BOD and AOD are supplementary angle.
Therefore
BOD +AOD = 180
BOD + 104 = 180
BOD= 180-104
BOD= 176
