Question 817337
a² + b² = c²   {Pythagorean Theorem}
a and b are the legs and c is the hypotenuse


18² + b² = 40²  {substituted into Pythagorean Theorem}
324 + b² = 1600   {evaluated exponents}
b² = 1276 {subtracted 324 from each side
b ≈ 35.72 {took square root of each side and rounded}


the other leg is approximately 35.72 meters
