HELP! DUE IN AN HOUR! SO CONFUED!! SOMEONE HELP EXPLAIN THIS TO ME!!!!

Answer 1

Answer:

No triangles are possible.

Step-by-step 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.
