cos(33^{\circ})

Step-by-step explanation:

Given

sin(57^{\circ})

Required

Determine an equivalent expression

In trigonometry:

sin(\theta)= cos(90^{\circ} - \theta)

In sin(57^{\circ})

\theta=57^{\circ}

Substitute 57^{\circ} for \theta

in sin(\theta)= cos(90^{\circ} - \theta)

sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})

sin(57^{\circ})= cos(33^{\circ})

Hence, the equivalent expression is: cos(33^{\circ})
