7. Non-Right Triangles

Classify the triangle, then solve: $A=60°,B=15°,c=6$.

The bearing of a lighthouse from a ship was found to be N 37° E. After the ship sailed 2.5 mi due south, the new bearing was N 25° E. Find the distance between the ship and the lighthouse at each location.

In Exercises 1–12, solve each triangle. Round lengths to the nearest tenth and angle measures to the nearest degree. If no triangle exists, state 'no triangle.' If two triangles exist, solve each triangle. C = 50°, a = 3, c = 1

Use the Law of Sines to find the length of side $a$ to two decimal places.

Use the Law of Sines to find the angle $B$ to the nearest tenth of a degree.
