Given:
A figure of right triangle with terminal angle
, base u, perpendicular v and hypotenuse r.
To find:
The value of
.
Solution:
In a right angle triangle,
![\sin \theta=\dfrac{Perpendicular}{Hypotenuse}](/tpl/images/1368/2100/a4c93.png)
Substituting Perpendicular = v and hypotenuse = r in the above formula, we get
![\sin \theta=\dfrac{v}{r}](/tpl/images/1368/2100/8c769.png)
The value of
is
.
Therefore, the correct option is B.
