Which of the following trigonometric values are negative? aligned & I. (-292^ ) & II. (-190^ ) & III. (-207^ ) & IV. (-222^ ) aligned

Options

  1. AII, III and IV
  2. BOnly III
  3. CI and III
  4. DII and III

Correct answer

D. II and III

Step-by-step solution

For option I, (-292^ )=- 292^ aligned & =- (360^ -68^ )=- 68^ & =-(-)=+ ve value aligned So, clearly (-292^ ) give + ve value. For option II, (-193^ )=- 193^ aligned & =- (180^ +13^ ) & =- 13^ (- ve value ) aligned For option III , (-207^ )= 207^ aligned & = (180+27^ ) & =- 27^ (-ve value) aligned For option IV, (-222^ )= (180^ +42^ )=+ 42^ (+ ve value )
