Acronym to remember the 3 basic trigonomic functions: 
Soh - Cah - Toa 
             opposite
sin = --------------------
            hypotenuse
              adjacent 
cos = -------------------
             hypotenuse
             opposite 
tan =  -----------------
             adjacent 
In your case, you can set up a sine trigonomic function, like this: 
Sin 48 = 10      (adjacent)
               -----  
                 x       (hypotenuse)
                       10
 (x) Sin 48 = ------ (x)
                         x
  (x) Sin 48 = 10 
 --------------   ------------- 
  Sin 48         Sin 48 
Plug in 10(sin)(48) into a calculator.
x = 7.43
I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D
        
             
        
        
        
Answer:
The first one 6+7i+(4-3i)  and the last one 12+6i-(2+2i) are equivalent
 
        
             
        
        
        
Answer:
X = 60
Y = 50
Step-by-step explanation:
The total degrees of a triangle is 180 degrees. For the middle triangle, 50+70=120 so 180-120=60. 
On the far right, Y=50 because you take 50 degrees from the middle triangle, and insert it there.
