Answer:
x = 130°
Step-by-step explanation:
The measure of the arc is double the measure of the inscribed angle that intercepts it.
2×65° = 130°
_____
Inscribed angle y intercepts the same arc (x), so has the same measure as the inscribed angle marked 65°. This will remain true even as the vertex of angle y approaches (and meets) the vertex of the marked 65° angle.
