Solve the triangle. A = 33Á, a = 19, b = 14
B = 23.7Á, C = 143.3Á, c 23.3
B = 23.7Á, C = 123.3Á, c 17.5
Cannot be solved
B = 23.7Á, C = 123.3Á, c 29.2

If it cannot be solved then why did you even ask?

A = 33°, a = 19, b = 14
sin B/b = sin A/a
sin B / 14 = sin 33 / 19
sin B = 14sin 33 / 19 = 0.4013
B = arcsin(0.4013) = 23.7°
A = 180° - 33° - 23.7° = 123.3°
c/sin 123.3 = 19/sin 33
c = 19 sin 123.3 / sin 33 = 29.2
The last option is the correct answer.
