Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h. Draw the altitude from A to BC. A lake between Towers A and C makes it difficult to measure the distance between them directly.

Repeat Step 2 using 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. Have each group member draw a different acute triangle ABC. However, in this case you may find more than one possible solution. Have each group member draw a different obtuse triangle.

What is the distance between Towers A and C? The other possibility for A is the obtuse supplement of Repeat Step 2 using expressions involving j, sin C, and sin A.

Draw the altitude from A to BC. Have each group member draw a different acute triangle ABC. Measure the angles and the sides of your triangle. A lake between Towers A and C makes it difficult to measure the distance between them directly. This is because two different angles—one acute and one obtuse— may share the same value of sine.

However, in this case you may find more than one possible solution. Upload document Create flashcards. You can add this document to your saved list Sign in Available only to authorized users.

Triangle Sum Theorem Sine Law in Acute Triangles. In wigh to find the distance along the northern branch, you need the measure of the third angle in the triangle. How far apart are the planes at this time? Geometry Chapter 7 Similarity Notes. Add to collection s Add to saved.

Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h. You can add this document to your study collection s Sign in Available only to authorized users. What proportion do you get when you eliminate j?

Did everyone get the same proportion in Step 4? Label the length of tdiangles side opposite A as a, the length of the side opposite B as b, and the length of the side opposite C as c.

# Lesson problem solving with right triangles worksheet answers

Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. Combine the two expressions by eliminating h.

Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as ttiangles. Where along the northern branch should they dig for the treasure?
