Question

Which of the following is equivalent to sin 37°?Group of answer choicescos 37°cos 53°sin 53°sin 63°

Answer 1

Recall that:

`sin\theta=cos(90^(\circ)-\theta).`

Therefore:

`sin37^(\circ)=cos(90^(\circ)-37^(\circ)).`

Simplifying the above result, we get:

`sin37^(\circ)=cos53^(\circ).`

Answer:

`\begin{equation*} cos53^(\circ). \end{equation*}`
