A lake between Towers A and C makes it difficult to measure the distance between them directly. Label the height h.

Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

How far apart are the planes at this time? Constructing and Analyzing Triangles.

However, in this case you may find more than one possible solution. What proportion trizngles you get when you eliminate j? Measure the angles and the sides of your triangle. For complaints, use another form. Label the length of the side opposite A as a, the length of the side opposite B as b, riggt the length of the side opposite C as c.

Triangle Sum Theorem Suggest us how to improve StudyLib For complaints, use another form.

In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. Therefore, you can find the sine of obtuse angles as well as the sines of acute angles and right angles. What is the distance between Solvimg A and C?

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.
