Question

State whether the given measurements determine zero, one, or two triangles. A = 61Á, a = 23, b = 24

Answer 1

The given measurements determine one triangles, A = 61Á, a = 23, b = 24 because the triangle can be defined using those 3 data, first is using the sine law to solve another angle. Then using cosine law to solve the third side. Lastly solving the 3rd angle by difference.
