Answer:
139
Step-by-step explanation:
first you need to find the x:
180= 8x + 51 + 6x - 25
180 - 51 +25 = 8x + 6x
154 = 14x
154/14 = x = 11
then you have to work out AOB:
8x +51
8(11) +51
88+51 = AOB = 139
to check your work, workout angle BOC and add both. angles together to check if you get 180:
BOC= 6x - 25
6(11) - 25
66 - 25 = 41
To check:
BOC + AOB = 180
41 +139 = 180
180 = 180
Hope this helps!
