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.
