Answer:
x = 48
y = 21
Step-by-step explanation:
To find the value of x and y, using the definition of supplementary angles, create an equation to find x and y as follows:
Finding y:-
 (supplementary angles definition)
Solve for y
 
Collect like terms
 
 
 
 
 
 
Finding x:-
 (supplementary angles definition)
Solve for x
 
Combine like terms
 
 
 
 

 
        
             
        
        
        
 EXPLANATION
Applying the Angles in Circles Theorem we can assevere that the measure of the unknown angles is given by the difference between 360 (By the Sum of Interior Angles of a Quadrilateral Theorem) and the angle 114 with both right angles.
 ? = 360 -114 - 90 - 90 
 ? = 66 degrees
The answer is 66 degrees

Answer:
4000
Step-by-step explanation:
let the marked price of the cycle be x
then x · (100% + 5% + 12%) = 4680
x = 
 = 4000
