Tell whether the triangle with the given side lengths is a right triangle. Measurements: 66 ft, 73 ft, 99 ft

Not a right triangle

Step-by-step explanation:

A right triangle obeys the Pythagorean theorem

a^2 + b^2 = c^2

66^2 + 73^2 = 99^2

4356 + 5329 = 9801

9685 = 9801

This is not true, so the three sides do not obey the Pythagorean theorem.

This means that the this is not a right triangle.
