Question

The length of the base of an isosceles triangle is 4 inches less than the length of one of the two equal sides of the triangles. If the perimeter is 32, find the three sides of the triangle. If x represents one of the equal sides of the triangle, then which equation can be used to solve the problem?

Answer 1

Let:
Answer:
Base = 8 inches and the other two sides are 12 inches each.
x = length of the triangle
y = length of one of the other two sides of the triangle

Therefore,perimeter==> 32 = x + y + y
==>x + 2y = 32
==>x = y - 4
==>y - 4 + 2y = 32
==>3y = 36
==>y = 12

and solving for "x"
==>x = 12 - 4
==>x = 8 Answer:
Base = 8 inches and the other two sides are 12 inches each.

That's all!!
