Question

A triangle has side lengths of 17 inches, 13 inches, and 28 inches.Does this triangle have an angle that measures exactly 90? explain

Answer 1

the triangle is obtuse...

Explanation:

17² + 13² = 458

28² = 784

If 17² + 13² equals 28² , so the triangle has right angle

If 17² + 13² less than 28² , so the triangle is obtuse

If 17² + 13² more than 28² , so the triangle is acute
