A land surveyor was measuring the distances from various pA land surveyor was measuring the distances from various points on a plot of land. Her measuring tool broke before the last leg measure was determined. Right triangle A B C. Side A C is x, side A B is 12 feet, and hypotenuse B C is 37 feet. The unknown length can be found using the Pythagorean theorem. The theorem states that the of the squares of the legs is the square of the hypotenuse. The missing length is feet. oints on a plot of land. Her measuring tool broke before the last leg measure was determined. Right triangle A B C.
