Creo que es A si no es porfavor dime.
Answer:
x = 3
Hope this helps!
Step-by-step explanation:
ΔABC is a 45°, 45°, 90° triangle. The longest side ( 6
) can be 
while AB and CB are x. Because 6 is equal to , you can see that x is equal to 6. Both AB and CB are equal to 6. ΔBDC ( CDB ) is a right triangle ( 30°, 60°, 90° ) so, BD = x, CB = 2x, and CD = 
. CB is equal to 6 so 2x = 6, x = 3.
