Answer:
x = 28
Explanation:
According to vertical angle theorm,
- when two lines interested each other, then the vertical angles formed are equal.
Here 4x + 10 and 122 are the vertical angles. i.e they are equal.
Subtract 10 from both sides,
- 4x + 10 - 10 = 122 - 10
- 4x = 112
Divide both sides by 4,
Henceforth the value of x is 28.
option B is the required answer.
