2. Solve for all missing sides and angles in each triangle. Note: You may find no
solution, one solution, or two solutions. (19 marks)
a. b = 12 m; $\angle B = 60^\circ$; C = 76°
b.
$\angle B = 51^\circ$; $\angle A = 71^\circ$; a = 9.8 km
c.
$\angle B = 34^\circ$; c = 20 cm; b = 15 cm
3. How many triangles are possible in each of the following situations? Clearly
explain how you determined your answer (method 1 or method 2). (6 marks)
a) c = 13.9m, b = 20.1m, $\angle C = 30.6^\circ$
b) b = 56.2km, $\angle B = 72.5^\circ$, $\angle C = 45.3^\circ$
c) c = 25mm, a = 7mm $\angle A = 55^\circ$
