Find the side $ a $ of a rhombus if height $h = 4$ and angle $\alpha = 90^o$.
Answer
$a = 4$
Explanation
To find side $ a $ use formula:
$$ \sin \left( \alpha \right) = \dfrac{ h }{ a } $$After substituting $ \alpha = 90^o $ and $ h = 4 $ we have:
$$ \sin( 90^o ) = \dfrac{ 4 }{ a } $$ $$ 1 = \dfrac{ 4 }{ a } $$ $$ a = \dfrac{ 4 }{ 1 } $$ $$ a = 4 $$This page was created using
