Is a triangle with sides 7 feet, 12 feet, and 14 feet a right, acute or obtuse triangle?

Acute

Step-by-step explanation:

This should be an acute triangle because if this was a right angle, then the three sides should be figured out by the Pythagorean Theorem.

An obtuse angle wouldn't be right either, you need an angle to be over 90.

<h3>What is the creditworthiness of a customer?</h3>

A customer is known to be one who can afford to pay for the product that they bought is said to be one who is creditworthy.
