Answer:

see below

Step-by-step explanation:

AOC = AOB + BOC   angle addition postulate

150 = 2x+ 6(x-3)  substitution

150 = 2x+ 6x-18  Distribution property

150 = 8x-18  Combine like terms

168 =8x   Addition property of equality  ( we added 18 to each side)

21 = x   Division property of equality( We divided each side by 8)
