Answer is False.
You can check by doing a^2 + b^2 = C^2
(7)^2 + (9)^2 = (11)^2
49 + 81 = 121
130 = 121
This is not a true statement, which makes it false. This is a triangle, but not a right one.
You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse of a right triangle.
Let's plug in the given values and check the validity of the statement.
a² + b² = c²
7² + 9² = 11²
This is false. Thus,
Answer:
False - a triangle with side lengths 7, 9, and 11 is not a right triangle.
in my opinion C is the answer
The second number after the decimal point- the 6
