To find an unknown side, we need to know the corresponding angle and a known ratio. We know that angle α=50°and its corresponding side a=10. We can use the following proportion from the Law of Sines to find the length of c. Similarly, to solve for b, we set up another proportion.

Answer 2

Answer:

SAS" is when we know two sides and the angle between them. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.
