Answer:

The correct answer is first option

Explanation:

Points to remember

Trigonometric ratio

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle ABC

BC = 5 cm, <A = 30° and <C = 90°

To find the correct equation

We have,

Tan θ = Opposite side/Adjacent side

Tan 30 =BC/AC

Tan 30 = 5/b

The correct answer is first option.
