Answer:
Option (c)
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
