Answer:
Step-by-step explanation:
The three pieces of fencing he has to use are 8 feet, 15 feet, and 20 feet long. For him to be able to make a right triangle with his fence, the length of the sides must form a Pythagoras triple. To determine if the lengths make a Pythagoras triple, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent².
Therefore
20² = 8² + 15²
400 = 64 + 225 = 289
Since they are not equal, it means that they do not form Pythagoras theorem, thus,.
He will not be able to make a right triangle with his fence.
