Question

I need to know if it’s A B C or D

Answer 1

10

Explanation:

We can calculate the value of x taking into account the following property of the angles inscribed within a circle, like this:

If we apply it in this case, we can plan the following equation:

`(5x+15+55)/(2)=60`

Solving for x:

`\begin{gathered} 5x+15+55=2\cdot60 \\ 5x=120-70 \\ x=(50)/(5) \\ x=10 \end{gathered}`

The value of x is 10
