On the packaging for a triangular sail, the edge measurements for the sail are listed as 7 ft × 15 ft × 17 ft. without unfurling the sail, you want to determine if the sail forms a right triangle, an acute triangle, or an obtuse triangle.

Obtuse triangle.

Step-by-step explanation:

1. By definition, you have:

- If the square of the length of the longest side is greater than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "obtuse".

-  If the square of the length of the longest side is less than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "acute".

-  If the square of the length of the longest side and the lenght of the other two sides are equal, then it is a right triangle.

2. Based on this information, you have:

3. The longest side is greater than the other two sides. therefore, it is an obtuse triangle.

The sail forms an obtuse angle.

Step-by-step explanation:

We will use Pythagorean theorem to classify triangle, which states:

Let us check our given sides using Pythagorean theorem.

We can see that the square of longest side is 289, which is greater than 274, therefore, the sail forms an obtuse angle.

what "following statement"?

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
