Answer:
sin θ =
Step-by-step explanation:
Given that,
cos θ =
From the trigonometric functions,
cos θ =
⇒ adjacent = , and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+
=
+
9 = 3 +
= 9 - 3
= 6
x =
Thus, opposite side =
So that,
sin θ =
=
Therefore,
sin θ =
