Answer:
root3/2
Step-by-step explanation:
Draw a equilateral triangle ABC and draw its altitude AD
Mark AB=BC=CA= a
and altitude AD = (root3)*a/2(formulae for the lenght of the altitude)
Now In triangle ABD
SinB = perpendicular/hypotenuse
Sin60(as all angles of a equilateral triangle are 60) = AD/AB
Sin60 = Root3*a/2 % a
sin60 = root3/2

try it yourself to understand
hope this will help you
