Problem 1: find the length of the unknown side of the triangle. a right triangle, one leg is 5 meters, one leg is unknown, and the hypotenuse is 11 meters. the length of the unknown side of the triangle is _ m. (simplify your answer. type an exact answer, using radicals as needed.) tip: a^2+b^2=c^2 problem 2: tip: a^2+b^2=c^2 find the length of the unknown side of each triangle. give the exact length and an approximate length. a right triangle, one leg is 8 millimeters, one leg is 8.1 millimeters, and the hypotenuse is unknown. the exact length of the unknown side is _ mm. (simplify your answer. type an exact answer, using radicals as needed. use integers or decimals for any numbers in the expression.) the approximate length of the unknown side is _ mm. (round to one decimal place as needed.)
