<span>the isosceles triangle has two equal sides </span> <span>let's analyze two cases </span> first case perimeter=22 cm <span>let's suppose that the known side of 6 cm is one of the two equal sides </span>perimeter=6+6+x 22=6+6+x-----> x=22-12----> x=10 cm
answer first case <span>the possible lengths of the other two sides are </span>6 cm 10 cm
second case let's suppose that the known side of 6 cm is the side that is not equal perimeter=22 cm perimeter=6+x+x 22=6+x+x----> 2x=22-6----> 2x=16-----> x=8 cm
answer second case the possible lengths of the other two sides are 8 cm 8 cm
