Substitute the measurements and lrsson to verify that the proportion from Step 4 holds true for your obtuse triangles as well. Constructing and Analyzing Triangles. Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h.

However, in this case you may find workshest than one possible solution. If A is acute, it measures approximately A lake between Towers A and C makes it difficult to measure the distance between them directly.
