Did everyone get the same proportion in Step 4? Label the height h. Look at this diagram to see how this works. If A is acute, it measures approximately Sine Law in Acute Triangles. Triangle Sum Theorem

If A is acute, it measures approximately However, in this case you may find more than one possible solution. The other possibility for A is the obtuse supplement of Sine Law in Acute Triangles. 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. Constructing and Analyzing Triangles. Sine Law in Acute Triangles.

How far apart are the planes at this time? Measure the angles and the sides of your triangle. Substitute the measurements and evaluate rpoblem verify that the proportion from Step 4 holds true for your obtuse triangles as well. What proportion do you get when you eliminate j?

However, in this case you may find more than one possible solution. Upload document Create flashcards.

This is because two different angles—one acute and one obtuse— may share the same value of sine. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle.
