If = 25^ + 25^ 25^ - 25^ and is in the third quadrant, then =

Options

  1. A200^
  2. B205^
  3. C225^
  4. D250^

Correct answer

D. 250^

Step-by-step solution

gathered If = 25^ + 25^ 25^ - 25^ = 1+ 25^ 1- 25^ = (45^ +25^ ) gathered is in the third quadrant, so aligned & = 70^ = (180^ +70^ )= 250^ & =250^ . & aligned
