Question

State if the three side lengths form an acute, obture, or right triangle 3 in 12 in and 13 in

Answer 1

Answer:

The triangle is obtuse.

Step-by-step explanation:

If a² + b² < c² , the triangle is obtuse.

If a² + b² = c² , the triangle is right triangle.

If a² + b² > c² , the triangle is acute.

3, 12, 13

3² + 12² < 13²

9 + 144 < 169

153 < 169 ⇒ the triangle is obtuse.
