How many triangles ABC can be constructed with angle A = 30^circ, b = AC = 6 cm and a = BC = 9 cm?

  1. 1
  2. 3
  3. 0
  4. 2
Answer

A) 1

The height from C is h = bsin A = 6 12 = 3 cm. Since a = 9 ge b = 6, the arc cuts the base line on only one side of A: one triangle. SLO M-09-B-30 · Knowledge
