Question 384281: the perimeter of a triangle is 31 cm. sides #1 and #2 have epual length, while side #3 is one centimeter shorter than twice the length of side #1. how long is each side Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! the perimeter of a triangle is 31 cm. sides #1 and #2 have epual length,
while side #3 is one centimeter shorter than twice the length of side #1.
how long is each side
:
Let x = side one
and x = side two
:
"side #3 is one centimeter shorter than twice the length of side #1"
therefore:
(2x-1) = side three
:
Perimeter:
x + x + (2x-1) = 31
You can do it now, I'm sure
