Find the angle $ \beta $ of a rhombus if angle $\alpha = 60^o$.
Answer
$\beta = 30^o$
Explanation
To find angle $ \beta $ use formula:
$$ \alpha + \beta = 90^o $$After substituting $ \alpha = 60^o $ we have:
$$ 60^o + \beta = 90^o $$ $$ \beta = 90^o - 60^o $$ $$ \beta = 30^o $$This page was created using
