Answer:



Step-by-step explanation:
I will solve this question with the attached triangle
From the attachment, we have:



Required
Solve the triangle
First, we calculate  using sine law:
 using sine law:

This gives:


Cross multiply


Divide both sides by 29

Take arcsin of both sides

 
Next, calculate  using:
 using:
 --- angles in a triangle
 --- angles in a triangle

Collect like terms


Next, calculate BC using sine laws

This gives:


Make BC the subject


 
        
             
        
        
        
One number is 26 the other is 23 
x+y=49
Y=x+3,X (now substitute it in the equation)
x+3+x=49
2x+3=49
2x=46. X=23
Y=x+3. Y=23+3 =26 for checking 23+26=49
        
             
        
        
        
They will have games on the same day in 21 days
        
             
        
        
        
Answer:
11x-2
Step-by-step explanation:
(3x2 - 4x + 6) + (7x - 2) This is the breakdown. (6 4x + 6)= 4x. + (7x-2) = 11x-2
