Find the angle $ \alpha $ of a rhombus if angle $\beta = 42^o$.
Answer
$\alpha = 48^o$
Explanation
To find angle $ \alpha $ use formula:
$$ \alpha + \beta = 90^o $$After substituting $ \beta = 42^o $ we have:
$$ \alpha + 42^o = 90^o $$ $$ \alpha = 90^o - 42^o $$ $$ \alpha = 48^o $$This page was created using
