Question

If m<AOC = 49°, m<BOC = 2x°+10°, and m<AOB = 4x°–15° find the degree measure of BOC and AOB.

mBOC = 18°; mAOB = 31°
mBOC = 28°; mAOB = 21°
mBOC = 21°; mAOB = 28°
mBOC = 31°; mAOB = 18°

Answer 1

I assume B is between A and C. Otherwise none of the answers can fit.

AOB + BOC = AOC
4x-15 + 2x+10 = 49
6x = 54
x = 9

BOC = 28
AOB = 21

Answer 2

Option 2 is correct! m<BOC=28 degrees; m<AOB=21 degrees
