Question

The value of x if

  1. 85°    
  2. 75°    
  3. 65°    
  4. 70°    

The correct answer is: 75°


    x plus 80 to the power of ring operator plus 85 to the power of ring operator plus 70 to the power of ring operator plus 50 to the power of ring operator equals 360 to the power of ring operator space left parenthesis s u m space o f space a l l space a n g l e s space a t space a n y space p o i n t space i s space e q u a l space t o space 360 right parenthesis
x plus 285 space ring operator to the power of blank equals 360 to the power of ring operator
x equals 360 to the power of ring operator minus 285 to the power of ring operator
x equals 75 to the power of ring operator
