Correct Answer - Option 2 : 0

**Concept used:**

cosec(90° – x) = sec x

tan(90° – x) = cot x

**Calculation:**

⇒ cosec(75° + x) – sec(15° – x) + tan(55° + x) – cot(35° – x)

⇒ cosec[90° – (15° - x)] – sec(15° – x) + tan[90° – (35° – x)] – cot(35° – x)

⇒ sec(15° – x) – sec(15° – x) + cot(35° – x) – cot(35° – x)

⇒ 0 + 0 = 0

**∴ The value of cosec(75° + x) – sec(15° **–** x) + tan(55° + x) – cot(35° **–** x) is 0**
