Question

If sin theta = 1/2 then sec theta is equal to

Answer 1

Hey mate hope it helps you...

sin∆ = 1/2

∆ = 30°

sec 30° = 2/√3

Answer 2

If sin θ = 1/2, then sec θ = 2/√3.

Given:

sinθ = 1/2

To find:

secθ =?

Solution:

We are given that,

sinθ = 1/2

θ = π/6

⇒ cosθ = cos π/6

= √3/2

Now,

sec θ = 1/cosθ = $\frac{1}{\sqrt{3} /2}$ = 2/√3

∴ sec θ = 2/√3
