ANSWER

139°

EXPLANATION

One of the interior angle properties of a parallelogram is that adjacent interior angles are supplementary.

This means that, the adjacent interior angles add up to 180°.

$m \angle \: B = m \angle \: D = 41$

Then

$m \angle \: C + m \angle \: D = 180 \degree$

$m \angle \: B + m \angle \:C= 180 \degree$

$\implies41 \degree + m \angle \:C= 180 \degree$

$\implies m\angle \:C= 180 \degree - 41 \degree = 139 \degree$

1st equation—x, substitute y:
3x + 2(x + 3) = 16 
3x + 2x + 6 = 16 
5x = 10 
x = 2 

y in the above equation: 
= 2 + 3 
= 5 

Answer: x = 2, y = 5
