Find the altitude $ h $ of an equilateral triangle if side $a = 4$.
Answer
$h = 2 \sqrt{ 3 }$
Explanation
To find height $ h $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ a = 4 $ we have:
$$ h = \dfrac{ \sqrt{ 3 } \cdot 4 }{ 2 } $$$$ h = \dfrac{ 4 \sqrt{ 3 } }{ 2 } $$ $$ h = 2 \sqrt{ 3 } $$This page was created using
