Answer:

9

Explanation:

The interior angle in a rectangle is equal to 90 degrees. If this angle consists of 6x and 4x, then we get the equation:


6x + 4x = 90$^(\circ)$


10x = 90$^(\circ)$


x = 9$^(\circ)$

Checking:


6x + 4x = 90$^(\circ)$


6 * 9$^(\circ)$ + 4 * 9$^(\circ)$ = 90$^(\circ)$


54$^(\circ)$ + 36$^(\circ)$ = 90$^(\circ)$


90$^(\circ)$ = 90$^(\circ)$
