Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. Does your work from Steps 1—5 hold true for obtuse triangles as well? For complaints, use another form.

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. Combine the two expressions by eliminating h. Look at this diagram to see how this works. Use the transitive property of equality to combine them into an worksheer proportion: 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.

What is the distance between Towers A and C? Suggest us how to improve StudyLib For complaints, use another form. A lake between Towers A and C makes it difficult to measure the distance between them directly.
