Given the right triangle below, use the sine function to write a trigonometric expression for the missing angle $\theta$.

• A. $\theta=\sin^{-1}\left(\frac{5}{13}\right)$
• B. $\theta=\sin^{-1}\left(\frac{12}{13}\right)$
• C. $\theta=\sin^{-1}\left(\frac{5}{12}\right)$
• D. $\theta=\sin^{-1}\left(\frac{13}{12}\right)$
