Answer:
x = 40° , y = 43° , z = 97°
Explanation:
the figure opposite sides parallel and is therefore a parallelogram.
• consecutive angles are supplementary
∠ C + ∠ D = 180°
x + 43 + 97° = 180°
x + 140° = 180° ( subtract 140° from both sides )
x = 40°
y and 43° are alternate angles and are congruent, then
y = 43°
• opposite angles are congruent
∠ B = ∠ D , that is
z = 97°
