perimeter of triangle = s+s+s
24=8+9+x
24=17+x
17+x=24
x=24-17
x=7cm
so the third side = 7cm
24=8+9+x
24=17+x
17+x=24
x=24-17
x=7cm
so the third side = 7cm

Hello,
are a, b, c the three sides of the triangle.
we have that:
P=a+b+c=24 and a=8, b=9
we calculate the third side:
c=P-a-b=24-8-9=7 cm
the thirs side measures 7 cm.
bye :-)
