Find the angle $ \beta $ of a rhombus if side $a = \frac{ 127 }{ 10 }$ and angle $\alpha = 40^o$.
Answer
$\beta = 50^o$
Explanation
To find angle $ \beta $ use formula:
$$ \alpha + \beta = 90^o $$After substituting $ \alpha = 40^o $ we have:
$$ 40^o + \beta = 90^o $$ $$ \beta = 90^o - 40^o $$ $$ \beta = 50^o $$This page was created using
