Answer:

$x=1$

Step-by-step explanation:

Because vertical angles are always equal, we want to solve $50x+10=70x-10$ .

We can add 10 to both sides to get $50x+20=70x$ .

We can subtract $50x$ from both sides to get $20=20x$ .

Lastly, we divide both sides by 20 to get $1=x$ .

So, $\boxed{x=1}$ and we're done!

The check is left as an exercise to the reader.

The value of x is 14

<h3>How to solve for x?</h3>

From the question, the lines from the center of the circle to the chords have equal measures of 9 units

This line divides a chord into equal segments, where each segment is 7 units

So, we have:

x = 7 + 7

Evaluate

x = 14

Hence, the value of x is 14
