The trigonometric expression sin 30° will be equal to cos 60°. Then the correct option is E.
<h3>How to convert the sine of an angle to some angle of cosine?</h3>
We can use the fact that:
sin(θ) = cos(90 - θ)
To convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).
The trigonometric expression sin 30° will be equal to
The sin 30° can be written as
sin 30° = cos(90° - 30)
sin 30° = cos 60°
Then the correct option is E.
