We will not be practicing this type of question here because there are lots of practice problems from the homework questions. Make sure you understand how to solve for the solutions (solution in one period and all solutions) Instead of solving trigonometric equation, we would like to practice on how to rewrite an angle as sum/difference of two special angles or rewrite an angle as half of a special angle.

You have been learning about the Law of Sines and the Law of Cosines. These two importantlaws allow you to solve for the unknown side lengths and angle measures in non-right triangles.Law of Sines Law of CosinesYou can use each of these laws only for certain types of triangles. You need to be careful whendetermining what data you have been given and what you are looking to solve for so that youchoose the correct law.Keep this information in mind as you read through the scenario below.Dionne works for a design firm that specializes in creating inviting and functional kitchenspaces. The majority of work in any kitchen involves the refrigerator, the stove, and the sink. Theplacement of these three appliances in a kitchen form what is known as the kitchen worktriangle. Dionne’s company offers both standard and custom work triangles. 3. Find all the angles in this work triangle. Show all of your calculations. Add the angle measuresto the sketch you created in question 1.
We use Law of Sines and Law of Cosines to solve for a triangle. When we say solve for a triangle, we need to find all three sides and three angles. However, when we apply Law of Sines, we will encounter some case called ambiguous case. This means there may be two triangles, one triangle, or no triangle with the given properties. Please keep this in mind when solving the following problems with Law of Sines: Two sides and an angle are given. Determine whether the given information results in one triangle, two triangles, or no triangle at all. Solve any resulting triangle(s). 1) a= 2, b= 3, B = 40° 2) a= 3, b= 7, B = 70° 3) a= 5, b = 3, B = 100°
