I hope it is helpful for you.

Answer 2

Answer:

x = 60°

y = 60°

z = 120°

Explanation:

We know that opposite angles and opposite sides of a parallelogram are equal.

So,

$\angle DAB =\angle BCD$

Therefore, y = 60°

$\angle ADC =\angle ABC \\ \\\angle ADC =z \: \: \: \: \: \: \: \: \: \: \: \:$

Also, the sum of adjacent angles of a parallelogram is 180°

Therefore ,

$\angle \: ADC +\angle DAB = 180^{\circ} \\ z + 60^{\circ} = 180^{\circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ z = {120}^{\circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Also,

Sum of linear pairs is always 180°.

Therefore,

$\angle \: ADE +\angle ADC = {180}^{\circ} \\ x + z = {180}^{\circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ x = {180}^{\circ} - {120}^{\circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ x = {60}^{\circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Therefore, the answer is :

x = 60°

y = 60°

z = 120°

Other Formulas:

1) Sum of Interior Angles of a polygon where n is the number of sides of polygon= (2n - 4) * 90°

2)Number of sides of a polygon when exterior angle is given =$\frac{360^{°}}{x}$

where x is the exterior angle

3) Sum of all exterior angles of any polgon = 360°

4) Number of diagonals of n sided polygon = $\frac{n(n-1)}{2}-n$

5) Sum of exterior and interior angle of a polygon of n sides = 180°
