Question 3 options:
in an equilateral triangle, all 3 sides are equal length, and the perimeter of an equilateral triangle is 3 times the length of one side.

if one side measures 9 + 3x, and the measure of another side is 5x – 5, what is the perimeter of the equilateral triangle?

90

Step-by-step explanation:

Given: Measure of one side of equilateral triangle =

Measure of another side of equilateral triangle =
