Find the angle $ \alpha $ of a rhombus if side $a = 14$ and angle $\beta = 49^o$.
Answer
$\alpha = 41^o$
Explanation
To find angle $ \alpha $ use formula:
$$ \alpha + \beta = 90^o $$After substituting $ \beta = 49^o $ we have:
$$ \alpha + 49^o = 90^o $$ $$ \alpha = 90^o - 49^o $$ $$ \alpha = 41^o $$This page was created using
