Question

Find the altitude of an equilateral triangle if one of its sites measures $10\sqrt{3}$ cm

Answer 1

Length of altitude of an equilateral triangle having side as $a$ cm is equal to $\frac{\sqrt{3}}{2}a$ cm

Here, $a=10\sqrt{3}$

Let $p$ be the length of required altitude.

$p=\frac{\sqrt{3}}{2}\times 10\sqrt{3}$

$=15$ cm
