Answer:

[tex]x = 10[/tex]

Step-by-step explanation:

Given

The attached circle

Required

Find the measure of x

From the attached image:

[tex]11x + 2[/tex] and [tex]-2 + 7x[/tex] form a semi-circle

So:

[tex]11x + 2 -2 + 7x = 180[/tex]

Collect like terms

[tex]11x + 7x = 180+ 2 -2[/tex]

[tex]18x = 180[/tex]

Solve for x

[tex]x = \frac{180}{18}[/tex]

[tex]x = 10[/tex]
