13. Non-Right Triangles

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.

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

An engineer wants to measure the distance to cross a river. If $B=30\degree$, $a=300$$ft$, $C=100\degree$ find the shortest distance (in $ft$) you’d have to travel to cross the river.
