PLZ HELP NEED ANSWERS FAST!!!
For problems 1-4, solve each triangle using either the Law of Sines or the Law of Cosines. If no triangle exists, write “no solution.” Round your answers to the nearest tenth. a = 12, b = 14, c = 21 A = 51°, b = 41, c = 40 A = 23°, B = 55°, b = 9 A = 18°, a = 25, b = 18 Jane is taking a ride around the lake. The route is shown below: Triangular diagram of Jane's ride What is the distance from the Beach to the Waterfront Restaurant?

Are there no angles given in the diagram? There's no way to find x just given the length of 2 sides. x will be less than (5.2+2.4) and greater than (5.2-2.4) miles.
answer 5=5.7 Miles x=5.7 Miles i just need the solutions to the first four
For number 1, use the cosine rule to first find an angle and go from there. 2, cosine rule again, to find side length a and go from there. 3, use the sine rule to find side length a, and so on. 4, use the sine rule to find angle B and so on.
Oh and for the ones where you're given two angles, you can find the third angle since A+B+C = 180
I dont know how to do the rules and for what angles and what not.....
http://www.mathsisfun.com/algebra/trig-sine-law.html http://www.mathsisfun.com/algebra/trig-cosine-law.html these both show pictures to show angle A, side a etc.
can you just give them to me? because i have six other assignments due in this subject and i will copy the rules you gave me and use them on my final in a few hours....
a/sin A = b/sin B = c/sin C c^2 = a^2 + b^2 - 2ab cos(C)
You still may need to look at the pictures to get an understanding of which side/angle is which.
