If =- 4 3 , then the value of is

Options

  1. A- 4 5 but 4 5
  2. B- 4 5 or 4 5
  3. C4 5 but - 4 5
  4. D1 5

Correct answer

B. - 4 5 or 4 5

Step-by-step solution

We have, =- 4 3 is less than 0 and 0 2 or 3 2 2 . = perpendicular hypotenuse =- 4 5 (i.e. - ve ) But, lies also between 3 2 and 2 = 4 5 also.
