We know that a triangle has three sides, all the same length (its equilateral, after all)
The equation to find the length of each side is
Perimeter divided by 3
or in this case
48.6 divided by 3=16.2cm (don't forget the unit)
Hope that helps :)

2 is the answer to this equation
Answer:
You should be able to prove it by saying that two of the angles are congruent because of the corresponding angles theorem.
