Answer:
7
Step-by-step explanation:
Since both chords are congruent and the distance of the x and 7 are equidistant from the center, then the value of x will also be 7.
Left side chord will have a value of y + 10
The right side chord will have a value of y + 10
Now since the right angles on both sides are equal, then x = 7.
