Ambiguous Case: Example
Let’s go through one more example before beginning your self-check.
Given , with A = 115°, a = 12, and b = 15, solve the triangle (round to the nearest tenth).
The diagram for this triangle is as follows:
Notice that side a of length 12 is not long enough to finish this triangle. That means there is no solution for this particular case.
We can justify this answer since A >=90 and a < b.
