Problema Solution
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 triangle. If the perimeter is 32, find the three sides of the triangle.
Answer provided by our tutors
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.
