Answer 1

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!
