Answer 2

The length of its altitude = 13.85 cm

Step-by-step explanation:

In a mathematics geometry is the branch of an equilateral triangle is a triangle in which whole three sides are equal and all three internal angles is also congruent to each other and are each $60^o$.

Property of equilateral triangle

• Area of equilateral; triangle = $\frac{\sqrt{3}}{4} \times (side)^2$.
• Number of vertices = 3.
• Number of edges = 3.
• Internal angle = $60^o$.
• It is a regular polygon.

Now applying area of equilateral triangle

$\frac{\sqrt{3}}{4} \times (side)^2$ = $\frac{1}{2} \times base\times altitude$

$\frac{\sqrt{3}}4}\times(AC)^2=\frac{1}{2}\times BC \times AD$

$AD=8\sqrt3$

$=13.85 cm$
