Answer: option (c)
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) =
here on the basis of angle P,
perpendicular = RQ
hypotenuse = PQ
Therefore,
sin (P)
= ½ …… [∵ angle P = 30°, sin(30°) = ½ ]
=
Thus, the value of sin(P) is represented by option(c): .
