9. Solve and find the unknown values

$\mathrm{\Delta }$\(ABC\) $\cong$ $\mathrm{\Delta }$\(DEF\) by \(ASA\) congruence condition with \(BC = EF\) and if \(∠B = 5x - 10\), \(∠C = y +\) 2, \(∠E =\) 110\(°\) and \(∠F =\) 50\(°\). Evaluate the value of \(x\) and \(y\).

 

 

The value of \(x\) is .

 

The value of \(y\) is .
