Answer:
if your looking for x then
Step-by-step explanation:
first add in the y by doing 10x+5(2x-3)=15 then 10x+10x-15=15 then 20x-15=15 then 20x=30 then divided by 20 for both sides which gets you x=30/20 or 1 1/3
 
        
                    
             
        
        
        
Answer: FIRST OPTION.
Step-by-step explanation:
 Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.
 By definition each interior angle of a Regular polygon,is:
  (In degrees)
  (In degrees)
 Where "n" is the number of sides of the polygon.
 
 Observe the Regular polygon given in the exercise. 
 Since it has 6 sides, you can conclude that it is an Hexagon. Then:
 
 Substituting into   and evaluating, you get:
  and evaluating, you get:
 
 Knowing this, you can write the following equation:
 
 Finally, you must solve for "x" in order to find its value. This is:
 
 
        
             
        
        
        

180 degress because a stranight angle equals that
