the perimeter of an equilateral triangle, whose side is x units, is thirty

Sagot :

Since the triangle is equilateral, meaning it has equal sides of x, add all the side to get the perimeter.

Perimeter = 30 units
Side = x units

x + x + x = 30
3x = 30

3x/3 = 30/3

x = 10 units

Therefore, each side has a length of 10 units.
