The triangle is obtuse.

Answer:  The given triangle is an obtuse triangle.

Step-by-step explanation:  Let ABC be the given triangle, where the side lengths are as follows :

AB=87~\textup{cm},~~BC=21~\textup{cm},~\textup{and}~CA=93~\textup{cm}.

We are to check whether ΔABC is acute, obtuse or right.

We know that ΔABC will be

(i) Acute, if AB² + BC² > CA²,

(ii) Obtuse, if AB² + BC² < CA²,

(iii) Right, if AB² + BC² = CA².

Now, we have

AB^2=87^2=7569,\\\\BC^2=21^2=441,\\\\CA^2=93^2=8649.

So,

AB^2+BC^2=7569+441=8010

Therefore, the given triangle is an obtuse triangle.

Troy is making a flag shaped like a square.Each side measures 12 inches.he wants to add ribbon along the edges. He has 36 inches
Orlov [11]
A square has 4 sides, and all sides have the same length.
If one side measures 12 inches, then the total length of all sides is 4 * 12 inches.
4 * 12 inches = 48 inches
All edges combined are a total of 48 inches.
He only has 36 inches of ribbon, so he does not have enough ribbon.
