Answer: F 
Explanation: you already know you have a 90° and the straight lines means it’s 180° so you need to find x and z which are the same so 2x + 90=180 which you would then subtract 90 from 180 which would be 90 then divide 90 by two which would be 45
        
             
        
        
        
I already answered this question, if you look back in your questions you should find this answered along with another one. I'll do it again just in case you don't find it.
Answer: 
{y,x} = {-4,-2} 
Expanation:
Solve by Substitution :
// Solve equation [1] for the variable  y 
 
  [1]    y = 2x 
// Plug this in for variable  y  in equation [2]
   [2]    -2•(2x) - 8x = 24
   [2]     - 12x = 24
// Solve equation [2] for the variable  x 
   [2]    12x = - 24 
   [2]    x = - 2 
// By now we know this much :
    y = 2x
    x = -2
// Use the  x  value to solve for  y 
    y = 2(-2) = -4
