Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =  , then
 , then
sin45° =  =
 =  =
 =  ( cross- multiply )
 ( cross- multiply )
x ×  = 9
 = 9 ( divide both sides by
 ( divide both sides by  )
 )
x = 9
 
        
             
        
        
        
Answer:
27.7 (rounded)
Step-by-step explanation:
 
        
                    
             
        
        
        
X=y+2
x=3y
2x=4y+2
4y+2=2(y+2)
4y+2=2y+4
2y+2=4
2y=2
y=1
x=3
1+3=4
Their sum is 4
Hope this helps :)
