Answer:

Option (c)

Step-by-step explanation:

There are six trigonometric ratios.

Sin theta, Cos theta, tan theta, cot theta, sec theta and cosec theta.

In a right angled triangle

Sin theta = perpendicular/hypotenuse

Cos theta= base / hypotenuse

Tan theta = perpendicular/ base

Cot theta = base/ perpendicular

Sec theta = hypotenuse/ base

Cosec theta= hypotenuse/ perpendicular

So, tan theta = Ry / Rx
