Answer:
x=123 
Step-by-step explanation:
x is across from the angle that measures 123 degrees. Therefore, they are vertical angles, and are congruent. 
x=123 
Additionally, 57 and x are on a straight line. This means they are supplementary and add to 180 degrees 
57*x=180 
Subtract 57 from both sides to get x by itself. 
x=123
 
        
             
        
        
        
Remember that there are 16 cups in a gallon.
The pipe leaks 1.5 cups each day, so in one week, or 7 days, the cup leaks 1.5 times 7 cups, which equates to 10.5 cups per week.
To find this number in gallons, divide 10.5 by 16.
This equals .65625 gallons per week.
Hope this helps!
