Answer: [tex]325^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle ABC=35^{\circ}[/tex]
A, C, and D lie on the circumference of the circle
from figure,
[tex]\angle ABC+x=360^{\circ}\quad [\text{angle around a point is 360}]\\\Rightarrow 35^{\circ}+x=360^{\circ}\\\Rightarrow x=325^{\circ}[/tex]
