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

Draw the altitude from A to BC. Add this document to saved. However, in this case you may find more than one possible solution. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. Add to collection s Add to saved. What is the distance between Towers A and C?

Measure the angles and the sides of your triangle. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Have each group member draw a different obtuse triangle. The other possibility for A is the obtuse supplement of A lake between Towers A and C makes it difficult to measure the distance between them directly.

Does your lesson from Steps 1—5 hold true for obtuse triangles as well? You can add this document to your study collection s Sign in Available only to authorized users.

If A is acute, it measures approximately However, in this case you may find more than one possible solution. Label the height h. Did everyone get the same proportion in Step 4? Repeat Step 2 using expressions involving j, sin C, and sin A.

In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. You can trianbles this document to your saved list Sign in Available only to authorized users. Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles.

Triangle Sum Theorem Draw the altitude from A to BC. Have each group member draw a different obtuse triangle. Have each group member draw a different acute triangle ABC.

A lake between Towers A and C makes it difficult to measure the distance between them directly. How far apart are the planes at this time? What is the distance between Towers A and C?

Look at this diagram to see how this works. The distance between Towers A and B is m. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as solviing.

## Lesson 12.2

This is because two different angles—one acute and one obtuse— may share the same value of sine. Measure the angles and the sides of your triangle.

Combine the two expressions by eliminating h. 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.
