2) The perimeter of an isosceles triangle is 16 inches.
The length of its base is 2 times the length of one of its other sides.
Let x = the length of each of its equal sides, and let y = the length of its base.
2x + y = 16
y = 2x
Solve these equations using substitution.
What are the measures of the sides of the triangle?
a) 3 in., 3 in., 6 in.
b) 4 in., 4 in., 8 in.
c) 4 in., 8 in., 8 in.
d) 6 in., 6 in., 8 in.
