### LESSON 12.2 PROBLEM SOLVING WITH RIGHT TRIANGLES WORKSHEET ANSWERS

Use the transitive property of equality to combine them into an extended proportion: Repeat Step 2 using expressions involving j, sin C, and sin A. Add this document to collection s. Label the length of the side opposite A as a, the length of the side opposite B as b, and the length of the side opposite C as c. Label the height h. However, in this case you may find more than one possible solution.

How far apart are the planes at this time? The other possibility for A is the obtuse supplement of Upload document Create flashcards. Draw the altitude from A to BC. The distance between Towers A and B is m.

Combine the two expressions by eliminating h. Draw the altitude from A to BC.

Substitute the measurements and evaluate to verify that the proportion from Step triangle holds true for your obtuse triangles as well. Label the height h.

Have each group member draw a different obtuse triangle. For complaints, use another form.

The other possibility for A is the obtuse supplement of Suggest us how to improve StudyLib For complaints, use another form. Measure the angles and the sides wihh your triangle. Constructing and Analyzing Triangles. Geometry Chapter 7 Similarity Notes. Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle.

Where along the northern branch should they dig for the treasure?

Did everyone get the same proportion in Step 4? What proportion do you get when you eliminate j?

Label the length of the side opposite A as a, the length of the side opposite B as b, and the length of the side opposite C as c. Add to collection s Add to saved.

Look at this diagram to see how this works. What is the distance between Towers A and C? However, in this case you may find more than one possible solution. How far apart are the planes at this time? Repeat Step 2 using expressions involving j, sin C, and sin A. Add this document to collection s.

Use your workshwet of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

Have each group member draw a different acute triangle ABC. Does your work from Steps 1—5 hold true for obtuse triangles as well? Sine Law in Acute Triangles. This is because two different angles—one acute and one obtuse— may share the same value of sine.
