This problem says that bryce measured the floor of his storage unit, which is rectangular.
00:05
It is three feet wide and five feet from one corner to the opposite corner.
00:09
How long is the storage unit? so since we're told that this is a rectangular shape, we know that we have right angles in all four corners of our floor of the storage unit.
00:21
And since we're dealing with right angles and we have that the width is three feet, but then the diagonal connecting corner to corners five feet, that means we can use pythagorean 3.
00:30
To figure out this unknown length because these are the legs of our right triangle, and this would be the hypotenuse.
00:37
So we can treat three feet as our a value in a squared plus b squared plus c squared, and then we can treat our x value as our unknown b value, and then we know the c value is the hypotenuse.
00:50
So a squared will be three squared plus b squared, which we've labeled as our unknown x squared, equal to c squared, which is five squared...
