Answer:
24°
Step-by-step explanation:
The unknown variable is x; 
 Now to find this parameter, we must understand that the sum of angles in a triangle is 180°. 
The base triangle has two given angles already. 
Now, the angle 110° is vertically opposite one of the interior angles. 
 Therefore; 
 110° + 46° + x° = 180° 
 x° = 180° - (156)
 x° = 24° 
The value of angle x° is 24°
