WebIn this activity, students will use sine, cosine, and tangent functions to find missing angle measures in right triangles. There is a total of 15 problems. In the first 9 problems, the students are given right triangles with two side lengths and a missing angle. There are 3 problems each requiring sine, cosine and tangent. WebHere are the steps you will take to find out the lengths of D, E. 1.Find out length of X using cosine rule in Δ A B X. 2.Knowing ∠ a, X, A, B, find out ∠ e, ∠ b using sine rule. 3. ∠ c = ∠ (between B,C) − ∠ b. So, ∠ c is known. 4.Repeat the whole procedure for Δ C X Y. Find out Y, ∠ d, ∠ f. 5. ∠ g, ∠ h are easily calculated now. 6. ∠ i is known.
