Answer:

139 degrees

Step-by-step explanation:

A straight angle is a 180 degree angle

<AOB+ <BOC= 180

8x+51+6x-25=180

14x+26=180

14x=154

x=11

m<AOB= 8x+51= 8(11)+51= 88+51= 139

Answer:

139⁰

Step-by-step explanation:

As AOC is a straight line ange :

AOB + BOC = 180

8x + 51 + 6x - 25 = 180

14x = 180 - 26

14x = 154

x = 11

AOB = 8(11) + 51 = 88 + 51 = 139⁰
