Find the altitude $ h $ of an equilateral triangle if side $a = 6 \sqrt{ 3 }$.
Answer
$h = 9$
Explanation
To find height $ h $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ a = 6 \sqrt{ 3 } $ we have:
$$ h = \dfrac{ \sqrt{ 3 } \cdot 6 \sqrt{ 3 } }{ 2 } $$$$ h = \dfrac{ 18 }{ 2 } $$ $$ h = 9 $$This page was created using
