Solution

We have the following sides given: 9, 14 and 12

For this case we can create the following notation:

a= 9, b= 12 and c= 14

And we can see this:

c^2 = 196

a^2 + b^2 = 81 + 225

Then:

[tex]c^2Then the answer is:

The triangle is Acute because the longest side squared is 196 which is less than than the sum of the squares of the other two sides which is 225
