Answer: see below
Step-by-step explanation:
3x-12=7x+8 ⇔ given
    -12=4x+8 ⇔ addition property of equality
    -20=4x ⇔ subtraction property of equality
       x=-5 ⇔ division property of equality
-----------------------
5(x-1)=4x+13 ⇔ given
5x-5=4x+13 ⇔ distributive property
  x-5=13 ⇔ subtraction property of equality
     x=18 ⇔ addition property of equality
 
        
             
        
        
        
Answer:
   
Step-by-step explanation:
Factor the denominator and cancel the common factor.
   
 
        
             
        
        
        
Use the Cosine Rule to find this
cos <B  = [b^2 - a^2 - c^2] /  -2ac 
               =  [ 4^2 - 10^2 - 11^2] / -2*10*11
               =   0.93182
so m < B  =   21.3 degrees to nearest tenth.  Answer
