### LESSON 12.2 PROBLEM SOLVING WITH RIGHT TRIANGLES WORKSHEET Combine the two expressions by eliminating h. If A is acute, it measures approximately For complaints, use another form. Your e-mail Input it if you want to receive answer. A lake between Towers A and C makes it difficult to measure the distance between them directly. The distance between Towers A and B is m. Use the transitive property of equality to combine them into an extended proportion: Does your work from Steps 1—5 hold true for obtuse triangles as well? Where along the northern branch should they dig for the treasure? You can add this document to your saved list Sign in Available only to authorized users. What is the distance between Towers A and C? Have each group member draw a different obtuse triangle. The other possibility for A is the obtuse supplement of For complaints, use another form. Add this document to saved. This is because two different angles—one acute and one obtuse— may share the same value of sine. Triangle Sum Theorem Sine Law in Acute Triangles. If A is acute, it measures approximately Look at this diagram to see how this works.

## Lesson 12.2

Add this document to collection s. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle.

LOMBA ESSAY FK UNUD

Use prblem transitive property of equality to combine them into an extended proportion: Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

Label the height h. What is the distance between Towers A and C?
