Failure is not an option. 9. Use the sum and difference identities to determine the exact value of the following expressions. a. \( \sin \left(160^{\circ}\right) \cos \left(25^{\circ}\right)-\cos \left(160^{\circ}\right) \sin \left(25^{\circ}\right) \) Failure is not an option. 9. Use the sum and difference identities to determine the exact value of the following expressions. a. \( \sin \left(160^{\circ}\right) \cos \left(25^{\circ}\right)-\cos \left(160^{\circ}\right) \sin \left(25^{\circ}\right) \) Solve the triangle. \( \mathrm{C}=110^{\circ} \) \( \mathrm{a} \approx \mathrm{L}^{\circ}, \quad \mathrm{B}=35^{\circ}, \quad \mathrm{C}=2 \) (Do not round until the final answer. Then round to the nearest tenth as needed.) Solve the triangle. \[ A=35^{\circ}, \quad B=35^{\circ}, \quad c=2 \] \( C=\square^{\circ} \) 8. Use the sum and difference identities to determine the exact value of the following expression: \( \sin \left(\frac{\pi}{3}-\frac{5 \pi}{4}\right) \) \( (5 \mathrm{pts} \). Solve the triangle. \( \mathrm{B}=42^{\circ} \) \( \mathrm{b} \approx 9.2 \) (Do not round until the final answer. Then round to the nearest tenth as needed.) \( \mathrm{c} \approx \square \). (Do not round until the final answer. Then round to the nearest tenth as needed.) b. \( \sin \left(110^{\circ}\right)+\sin \left(110^{\circ}\right) \) Dada la función \( \csc \theta=\frac{13}{12} \), determina a la función \( \cot \theta \) Seleccione una: a. \( \frac{12}{5} \) b. \( \frac{5}{13} \) c. \( \frac{5}{12} \) d. \( \frac{13}{5} \) Failure is not an option. 7. Use the sum-to-product identities to rewrite the following expressions as a produc a. \( \cos (2 \theta)-\cos (6 \theta) \) Una escalera de 10 m está recargada sobre una pared. ¿Qué altura alcanza si forma con el suelo un ángulo de \( 71^{\circ} \) ?
