Answer:
Explanation:
Given:
[tex]\sin\theta=\frac{\sqrt{2}}{2}[/tex]
Take the arcsin of both sides of the equation:
[tex]\begin{gathered} \arcsin(\sin\theta)=\arcsin\left(\frac{\sqrt{2}}{2}\right) \\ \theta=45\degree \end{gathered}[/tex]
The exact acute angle of the given function value is 45 degrees.
