Answer:
[tex]X=25.98cm[/tex]
Step-by-step explanation:
From the question we are told that:
Length of each side [tex]l=30cm[/tex]
Let the triangle be divide by two form a right angle triangle with base angles as [tex]90 \textdegree[/tex](angle of perpendicularity) and [tex]60 \textdegree[/tex] (angle on each vertices of an equilateral triangle)
Generally the equation for the Altitude X is mathematically given by
Trigonometric Rule
[tex]X=30sin60[/tex]
[tex]X=15\sqrt{3}[/tex]
[tex]X=25.98cm[/tex]
