9Work Shown:a = unknown  = leg #1b = 12  = leg #2c = 15 = hypotenusePlug those values into the pythagorean theorem and solve for a a^2 + b^2 = c^2 a^2 + (12)^2 = (15)^2   substitutiona^2 + 144 = 225 a^2 = 225 - 144  ... subtracting 144 from both sidesa^2 = 81 a = sqrt(81)   applying square root to both sidesa = 9...
