Find the angle $ \gamma $ of a triangle if angle $\alpha = 54^o$ and angle $\beta = 90^o$.
Answer
$\gamma = 36^o$
Explanation
To find angle $ \gamma $ use formula:
$$ \alpha + \beta + \gamma = 180^o $$After substituting $ \alpha = 54^o $ and $ \beta = 90^o $ we have:
$$ 54^o + 90^o + \gamma = 180^o $$ $$ \gamma + 144^o = 180^o $$ $$ \gamma = 180^o - 144^o $$ $$ \gamma = 36^o $$This page was created using
