Question

Each side of the equilateral triangle shown is 3 inches long. What is the height of the triangle?

Answer 1

•  measure of the side:   s = 3 in


You can find the height  h  by this formula:

          s · √3
h  =  ————
              2

          3 · √3
h  =  ————
              2

           3√3
h  =  ————  in     (exact value)
             2


Using  √3 ≈ 1.73,

           3 · 1.73
h  ≈  —————
                2

           5.19
h  ≈  ————
             2

h ≈ 2.60 in   (approximate value)


I hope this helps. =)
