1. Solve:
A=?, a=3, B=?, b=4, C=53°, c=?
2. Use law of sines to solve for all possible triangles that satisfy A=43.1°, a=186.2, b=248.6
Currently I have: C=206.96, B=6.32, and c=130.58
3.Sketch/Solve:
Two ships leave port at the same time. One travels 20 mi/hr N32°E and the other 28mi/hr S42°E. How far apart are they after 2 hours?
For these two I included my sketches of the given info:
4. Sketch/Solve:
A satellite orbiting the earth passes directly overhead at observations stations in Phoenix and Los Angeles, 340 miles apart. At an instant when the satellite is between these 2 stations, its angle of elevation is simultaneously observed to be 60° at Phoenix and 75° at LA. How far is the satellite from LA?
so far I have: A=60, a = 416.41, B=75, b=464.45, C=45, c=340
5. Sketch/Solve:
A pilot is flying over a straight highway. He determines the angles of dpression to two mileposts (A and B), 5 miles apart, to be 32° and 48° respectively. Find the distance of the plane from milepost A, and the elevation of the plane. (Assume plane is inbetween mileposts.)
so far I have: A=32, B=48, C=100, c=5. Then I extended the left side of triangle ABC, to create ACD, with A having a 58 degree angle, C having a 32 degree angle, and D having a 90 degree angle.
Thanks.
Edit: Nevermind
