Find the angle $ \beta $ of a rhombus if side $a = 60$ and angle $\alpha = 65^o$.
Answer
$\beta = 25^o$
Explanation
To find angle $ \beta $ use formula:
$$ \alpha + \beta = 90^o $$After substituting $ \alpha = 65^o $ we have:
$$ 65^o + \beta = 90^o $$ $$ \beta = 90^o - 65^o $$ $$ \beta = 25^o $$This page was created using
