The length of one leg of a right triangle is 9 meters. the lengths of the other two sides are consecutive integer numbers of meters. what is the number of meters in the perimeter of the triangle?
suppose the other leg is x, the hypotenuse is then x+1 using the Pythagorean theorem, 9²+x²=(x+1)² 81+x²=x²+2x+1 2x=80 x=40 the hypotenuse is 41+1=41 peremeter: 41+40+9=90
