A body is in equilibrium under the action of three coplanar forces `P,Q and R` as shown in figure. Select the correct statement.

A

`(P)/(sin alpha) = (Q)/(sin beta) = (R )/(sin gamma)`

B

`(P)/(cos alpha) = (Q)/(cos beta) = (R )/(cos gamma)`

C

`(P)/(tan alpha) = (Q)/(tan beta) = (R )/(tan gamma)`

D

`(P)/(sin beta) = (Q)/(sin gamma) = (R )/(sin alpha)`
