Answer:
No triangles are possible.
Step-by-step explanation:
<u>Given</u>:
- 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 <u>sum to 180°</u>.
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.
