Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. The distance between Towers A and B is m. The other possibility for A is the obtuse supplement of Have each group member draw a different acute triangle ABC. Triangle Sum Theorem

Combine the two expressions by eliminating h. For complaints, use another form. The other possibility for A is the obtuse supplement of What proportion do you get when you eliminate j? Add to collection s Add to saved.

Look at this diagram to see how this works. The other possibility for A is the obtuse supplement of Measure the angles and the sides of your triangle. Add this document to collection s. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. What proportion do you get when you eliminate j?

For complaints, use another form. Sine Law in Acute Triangles.

## Lesson 12.2

Have each group member draw a different obtuse triangle. Draw the altitude from A to BC.

Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. This is because two different angles—one acute and one obtuse— may share the same value of sine.

The distance between Towers A and B is m. Use the transitive property of equality trixngles combine them into an extended proportion: Triangle Sum Theorem Suggest us how to improve StudyLib For complaints, use another form.
