Question

Given that stack R with rightwards arrow on top text = end text stack text P end text with rightwards arrow on top text + end text stack text Q end text with rightwards arrow on top. And stack R with rightwards arrow on top makes angle alpha with stack P with rightwards arrow on top and beta with stack Q with rightwards arrow on top. Which of the following relations is correct?

  1. alpha cannot be less than beta    
  2. alpha < beta if P < Q    
  3. alpha < beta if P > Q    
  4. alpha < beta if P = Q    

The correct answer is: alpha < beta if P > Q
