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

Where along the northern branch should they dig for the treasure? However, in this case you may find more than one possible solution. Draw the altitude from A to BC. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles.

Repeat Step 2 using expressions involving j, sin C, and sin A. Add this document to collection s. Triangle Sum Theorem In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. A lake between Towers A and C makes it difficult to measure the distance between them directly. Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

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 lessson What is the distance between Towers A and C? Measure the angles and the sides of your triangle. Did everyone get the same proportion in Step 4? What proportion do you get when you eliminate j? However, in this case you may ledson more than one possible solution.

Have each group member draw a different obtuse triangle. Suggest us how to improve StudyLib For complaints, use another form. Your e-mail Input it if you want to receive answer.

## Lesson 12.2

Constructing and Analyzing Triangles. Draw the altitude from A to BC.

Have each group member draw a different acute triangle ABC. If A is acute, it measures approximately The other possibility for A is the obtuse supplement of A lake between Towers A and C makes it difficult to measure ;roblem distance between them directly. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle.

Label the length of the solvong 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.

# Lesson problem solving with right triangles worksheet answers

Combine the two expressions by eliminating h. Add this document to collection s. Geometry Chapter 7 Similarity Notes. Does your work from Steps 1—5 hold true for obtuse triangles as well? Repeat Step 2 wihh expressions involving j, sin C, and sin A. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Label the height h. Look at this diagram to see how this works. For complaints, use another form.

Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. Upload document Create flashcards. Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h. How far apart are the planes at this time?
