<PRE><B>Question 245692</B>
An isosceles triangle has two sides that are equal.
so the perimeter=2L+B where L=equals one of the equal sides and b= the base
2L+B=41 cm.
B=2L-23cm.
so we can substitute 2L-23 for B
2L+2L-23=41
4L-23=41
add 23 to both sides
4L=64
divide both sides by 4
L=16
B=2L-23
B=2*(16)-23
B=32-23
B=9
So we have 16 cm., 16 cm. , and 9 cm.
check
16+16+9=41
41=41
