Find the side $ a $ of a pyramid if lateral edge $e = 65$ and base diagonal $d = 66$.
Answer
$a = 33 \sqrt{ 2 }$
Explanation
To find side $ a $ use formula:
$$ d = \sqrt{ 2 } \cdot a $$After substituting $ d = 66 $ we have:
$$ 66 = \sqrt{ 2 } \cdot a $$ $$ a = \dfrac{ 66 }{ \sqrt{ 2 } } $$ $$ a = 33 \sqrt{ 2 } $$This page was created using
