Answer:

This is a ssa situation, no triangle is possible.

Step-by-step explanation:

"SSA" means "Side, Side, Angle".

In an SSA triangle, we are given two sides and an angle that is not the angle between the given sides.

In triangle ABC:

  • A, B and C are the interior angles.
  • a, b and c are the sides opposite the corresponding interior angles.

Given:

  • m∠A = 44°
  • side a = 12.6 cm
  • side b = 19 cm

The angle that is between the sides a and b is angle C.

Therefore, as angle A is not the angle between the given sides, ΔABC is an SSA triangle.

Law of Sines

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

To determine if any triangles are possible, substitute the given values into the Law of Sines to find angle B:

[tex]\implies \sf \dfrac{\sin 44^{\circ}}{12.6}=\dfrac{\sin B}{19}[/tex]

[tex]\implies \sf \sin B=\dfrac{19\sin 44^{\circ}}{12.6}[/tex]

[tex]\implies \sf \sin B=1.0475007...[/tex]

As -1 ≤ sin B ≤ 1, there is no solution for angle B.

Therefore, although this is an SSA situation, no triangle is possible.
