a^2 + b^2 = c^2...where a and b r the legs and c is the hypotenuse
35^2 + b^2 = 37^2 1225 + b^2 = 1369 b^2 = 1369 - 1225 b^2 = 144...by taking the sqrt of both sides, this eliminates the ^2 on left b = sqrt 144 b = 12...so ur other leg is 12 <==
use Pythagorean theorem a^2 + b^2 = c^2 Since 37 is the hypotenuse it will go in for 'c'. a^2 + 35^2 = 37^2 a^2 + 1225 = 1369 Subtract 1225 from both sides. a^2 = 144 Take the square root of both sides. a = 12 The missing length is 12
