An isosceles triangle has two sides of equal
length. The third side is 5 less than twice the
length of one of the other sides. If the perimeter of
the triangle is 23 cm, what is the length of the third
side?
if the triangle is 23cm and two sides are equal you need to determine the two sides with would be 7 and 7 then double one side which is 14 and the third side being 9 is 5 less then twice one side
