The perimeter of an isosceles triangle is 37 in. The lengths of the two
equal legs are 6 in. less than 3 times the length of the base. Find the lengths of the three sides.
37=2L+2W
W=3W6
do i have this equation wrote right
when i try to solve it
the answers i get is
w=3
l=15.5
I feel like i maybe missing some thing here can anyone help me
Your equation 37=2L+2W would be used for a rectangle, not a triangle.
let the base be x in
then the other sides are 3x6 each
now add them up
3x6 + 3x6 + x = 37
..
..
x=7
so the base is 7, the other sides are 15 each.
everything checks out!
