Answer:

No triangles are possible.

Explanation:

Given:

  • m∠A = 18°
  • side c = 19 in
  • side a = 4 in

In a triangle ABC:

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

The interior angles of a triangle sum to 180°.

Given m∠A = 18°, the sum of angles B and C is:

⇒ m∠B + m∠C = 180° - 18° = 162°

As there is no answer option where the sum of angles B and C equals 162°, no triangles are possible from the given answer options.
