### LESSON 12.2 PROBLEM SOLVING WITH RIGHT TRIANGLES WORKSHEET

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. Use the transitive property of equality to combine them into an extended proportion: This is because two different angles—one acute and one obtuse— may share the same value of sine. Draw the altitude from A to BC. Does your work from Steps 1—5 hold true for obtuse triangles as well?

Have each group member draw a different obtuse triangle. This is because two different angles—one acute and one obtuse— may share the same value of sine. Use the transitive property of equality to combine them into an extended proportion: Your e-mail Input it if you want to receive answer. Add this document to collection s.

Repeat Step 2 using expressions involving j, sin C, and sin A. Where along the northern branch should they dig for the treasure? Add to collection s Add to saved. Look at this diagram to see how this works.

Does your work from Steps 1—5 hold true for obtuse triangles as well? If A is acute, it measures approximately How far apart are the planes at this time?

## Lesson 12.2 problem solving with right triangles worksheet answers

A lake between Towers A and C makes it difficult to measure the distance between them directly. You can add this document to your saved list Sign in Available only to authorized users.

Constructing and Analyzing Triangles. Add this document to collection s. Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

Triangle Sum Theorem What is the distance between Towers A and C? 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.

Have each group member draw a different acute triangle ABC. Measure the angles and the sides of your triangle. The other possibility for A is the obtuse supplement of Label the height h. For complaints, use another form. Add this document to saved.

The distance between Towers A and B is m. Have each group lesskn draw a different obtuse triangle. Your e-mail Input it if you want to receive answer.

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. Did everyone get the same proportion in Step 4?

Combine the two expressions by eliminating h. Draw the altitude from A to BC. Use the transitive property of equality to combine them into an extended proportion: Suggest us how to improve StudyLib For complaints, use solvinf form. This is because two different angles—one acute and one obtuse— may share the same value of sine. Sine Law in Acute Triangles.
