Find the values of $a$ and $b$ if $ \mathrm{AB} \| \mathrm{DE} $.
"
Given:
\( \mathrm{AB} \| \mathrm{DE} \).
To do:
We have to find the values of $a$ and $b$.
Solutions:
$AB \parallel DE$ and $AC$ is a transversal, then
$\angle a=\angle BAC=49^o$ (Alternate angles are equal)
$AB \parallel DE$ and $BC$ is a transversal, then
$\angle b=\angle ABC=62^o$ (Alternate angles are equal)
The values of $a$ and $b$ are $49^o$ and $62^o$ respectively.
