Let's Check Our Work 57.71 ft. 13.96 ft. Let's check to make sure the Pythagorean Theorem works for this right triangle as well. 56 ft. Enter 13.962 +562 in the left side of the table. Enter 57.712 in the right side of the table. 14° (Notice how they're not *exactly* the same. Because we rounded the values for the two sides we found, our two sides of the Pythagorean Theorem are off by a slight rounding error. It doesn't mean we made a mistake, it's just what is called a "rounding error"). The more decimals we used for each irrational side length, the more accurate our Pythagorean Theorem check would be Sum of Legs Squared Hypotenuse Squared
