6, 15, 16

acute

right


obtuse


not a triangle

Answer 1

Answer:

• A. Acute

Step-by-step explanation:

Use Pythagorean to verify:

• 16² vs 6² + 15²
• 256 vs 36 + 225
• 256 vs 261

Since 256 < 261, the angle opposite to side with 16 units is smaller than 90°, all interior angles are smaller than 90°.

• The triangle is acute
