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. Sine Law in Acute Triangles. Repeat Step 2 using expressions involving j, sin C, and sin A. The other possibility for A is the obtuse supplement of If A is acute, it measures approximately For complaints, use another form.

However, in this case you may find more than one possible solution.

Constructing and Analyzing Triangles. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Geometry Chapter 7 Similarity Notes. Your e-mail Input it if you want to receive answer. 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.

Measure the angles and the sides of your triangle. Where along the northern branch should they dig for the treasure?

What is the distance between Towers A solvinv C? In order to find the distance along the northern branch, you need the measure of the third angle in the triangle.

Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h. Does your worksneet from Steps 1—5 hold true for obtuse triangles as well?
