How you considered that the base as Cos theta?

@Manoj.
Angle touch to horizontal axis i.e. base hence it is cos.

V.R = (Distance moved by effort)/(Distance moved by lode).
Since effort is vertical so it will be P sinθ and load will be:
I = (p sinθ)^2+(p cos θ)^2
Since effort is vertical so it will be P sinθ and load will be:
I = (p sinθ)^2+(p cos θ)^2

Since, v = u+at,
v1= gsin (theta)t, u = 0, a = g cos(90-theta) = g sin(theta).
v2 = gt.
So, v2/v1 = sin(theta).
v1= gsin (theta)t, u = 0, a = g cos(90-theta) = g sin(theta).
v2 = gt.
So, v2/v1 = sin(theta).

It is simply inclination with respect to X & Y axis. So angle made with Y axis is Sin θ.

Which one is correct? Please explain the correct answer.

When the angle is given with respect to horizontal, then in Y axis sin theta is taken.

Sin (theta) is correct.

The answer should be cosec (theta).
The distance moved by effort is the length of the inclined plane, the distance moved by the load is the vertical distance if you resolve these you get X/Xsin (theta) which is 1/sinX.

I think tan(theta) is correct.
