Answer:
Obtuse Triangle.
Step-by-step explanation:
The Pythagorean Theorem helps us to Classify Triangles according to its sides.
If \(a^{2}+b^{2}>c^{2}\), then lengths a, b, and c make up an acute triangle.
If \(a^{2}+b^{2} then lengths a, b, and c make up the sides of an obtuse triangle.
If \(a^{2}+b^{2}=c^{2}\) Then the length a,b,c make a right triangle.
The given sides are 5,7 and 11.
\(5^{2}+7^{2}<11^{2}\)
Or 74<121
Or \(a^{2}+b^{2}
So given triangle is obtuse triangle.
