x=8

angle AOB = 36

angle BOC = 54

Hope This Helps!

∠ AOB = 36°

Step-by-step explanation:

Since OA is perpendicular to OC, then

∠ AOB + ∠ BOC = 90 , substitute values

6x - 12 + 3x + 30 = 90

9x + 18 = 90 ( subtract 18 from both sides )

9x = 72 ( divide both sides by 9 )

x = 8

Thus

∠ AOB = 6x - 12 = 6(8) - 12 = 48 - 12 = 36°

27/3 = 9 so 270/3 = 90
