Answer:
![c = 77.6](https://tex.z-dn.net/?f=%20c%20%3D%2077.6%20)
Step-by-step explanation:
You may have entered the measure of a side as the measure of an angle.
![\dfrac{\sin A}{a} = \dfrac{\sin C}{c}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Csin%20A%7D%7Ba%7D%20%3D%20%5Cdfrac%7B%5Csin%20C%7D%7Bc%7D%20)
![\dfrac{\sin 75^\circ}{150} = \dfrac{\sin 30^\circ}{c}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Csin%2075%5E%5Ccirc%7D%7B150%7D%20%3D%20%5Cdfrac%7B%5Csin%2030%5E%5Ccirc%7D%7Bc%7D%20)
![c\sin 75^\circ = 150 \sin 30^\circ](https://tex.z-dn.net/?f=%20c%5Csin%2075%5E%5Ccirc%20%3D%20150%20%5Csin%2030%5E%5Ccirc%20)
![c = \dfrac{150 \sin 30^\circ}{\sin 75^\circ}](https://tex.z-dn.net/?f=%20c%20%3D%20%5Cdfrac%7B150%20%5Csin%2030%5E%5Ccirc%7D%7B%5Csin%2075%5E%5Ccirc%7D%20)
![c = 77.6](https://tex.z-dn.net/?f=%20c%20%3D%2077.6%20)
You are correct. Good job!
