Amare Harrington · Answer 1

X is the variable for the length of the sides.

Because a equalilateral ∆ has 3 equal sides, they can be represented by one term (x)

Stewart · Answer 2

The perimeter of an object is equal to its sides added up. Because this is a triangle, it will have 3 equal sides. Since the triangle has 3 equal sides, its perimeter will be equal to one of its side lengths * 3.

Because the perimeter will be equal to one of its side lengths * 3, x is equal to one of the triangle's side lengths.
