The actual length of a soccer field is 92 yards. The measuring device measured 90.7 yards, therefore it is defective. What is the percent error of measurement of the defective measuring device to the nearest tenth?

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

you can't solve x because it is 2 linear equation and you only have one equation
