Suppose A is given. If only one value of ( A 2 ) is possible, then A must be

Options

  1. AAn odd multiple of 90^
  2. BA multiple of 90^
  3. CAn odd multiple of 180^
  4. DA multiple of 180^

Correct answer

C. An odd multiple of 180^

Step-by-step solution

Given, A 2 has only one value. We know, A =2 ^2 ~A 2 -1 2 ^2 ~A 2 = A +1 ~A 2 = A +1 2 Since, A 2 is single value, A+1 2 =0 A =-1 So, A is an odd multiple of 180^ .
