Question

Please answer this question.

Answer 1

Answer:

1

Explanation:

Given

Secθ - Tanθ = 1/5 ----- (1)

We know that,

Sec²θ - Tan²θ = 1

⇒ (Secθ + Tanθ) (Secθ - Tanθ) = 1

⇒ (Secθ + Tanθ) × 1/5 = 1 (From 1)

⇒ (Secθ + Tanθ) = 5 ----- (2)

Now, from (2), we get

∴ √{(Secθ + Tanθ)/5} = √(5/5) = 1

Answer 2

Answer:

answer is 1

Explanation:

By identity sec²θ - tan²θ = 1
