Solving triangles

Question

Do not solve, but determine how many triangles are possible in each case. A = 98˚ b = 13 a = 12

Answer 1

A = 98˚ b = 13 a = 12

Since A is a an obtuse angle, its opposite side should be the longest side, but is not.

Therefore this configuration cannot be a triangle.

Unless these dimensions are changed, no other triangle can be formed.
