Answer:
the right answer is 2 < s< 18 
Step-by-step explanation:
The Third side of the triangle must be greater than the difference of the other two sides which is 10 -8= 2 and smaller than the sum of the other two sides of the triangle which is 10+8= 18.
so third side should be greater than 2 and less than 18. 
So right answer is 2 < s< 18 
 
        
             
        
        
        
Vertically opposite angles are equal
With this information we can form an equation
2x+14=60
Subtract 14 from both sides
2x=46
Divide both sides by 2
X=23
x = 23 degrees

8 1/8 total miles walked.
Step-by-step explanation:
I like to make fractions simple so I would do this,
9/4 plus 47/8
Take 8 and your common denominator and solve.
18/8 plus 47/8 = 65/8 which can be put as 8 1/8.
