Answer: option (c) \frac{RQ}{PQ}  

Step-by-step explanation:

Given data:

In ∆ PQR, we are given

∠QRP = 90°

∠RPQ = 30°

∠PQR = 60°

To find: value of sin (P)

Solution:

In ∆ PQR, using the trigonometry properties of a triangle, we get

sin (P) = \frac{Perpendicular}{Hypotenuse}

here on the basis of angle P,  

perpendicular = RQ

hypotenuse = PQ  

Therefore,  

sin (P)

= ½  …… [∵ angle P = 30°, sin(30°) = ½ ]

= \frac{RQ}{PQ}

Thus, the value of sin(P) is represented by option(c): \frac{RQ}{PQ} .
