Group Discussion

Set Up, Predict & Post

For this discussion, you will work in groups to solve for a in the oblique triangle ABC; AB = 30; AC = 15 and angle B = 20∘ 

For your initial post, use the Canvas Equation Editor to type out the two equations substituting the numbers from the diagram.

• First, type out the Law of Sines set of relationships.

• Next, type out the most appropriate version to use the Law of Cosines for this solution.

Post both equations and make a prediction of which method will be easier to use in finding a solution and why you think that is the case.

Make your initial post by the fourth day of the module week. You must make your initial post before you can see the posts of your classmates.

Solve & Reply

Now, for your first reply, solve for  a using the Equation Editor. If your birthday is between:

• January and June, use the Law of Cosines

• July and December, use the Law of Sines

Remember, post your solution and your step-by-step work to your initial post- not someone else's. 

Review & Discuss

After you have completed your posts, review the other members' posts. Note whether your answers match the solutions of your fellow group members. Reply to at least two with corrections to their solutions or explanations or observations about their solutions.

Engage in a dialogue about one or more of the following:

• Did we all get the same value for a?

• If, not where are the errors in the proposed solutions (mine or classmates')?

• How can you be sure your solution is correct?

• Compare the two methods - Law of Sines and Law of Cosines to confirm or refute your idea of which would be easier.

• Have we each given thorough explanations for our work?
