Answer:

$\\\\$

x = 20°

y = 130°

$\\\\$

Explanation:

$\\\\$

We know that, the opposite angles of a parallelogram are equal.

$\\$

5x + 30° = y ......(1)

$\\\\$

We also know that, sum of adjacent angles of a parallelogram is 180°.

$\\$

5x + 30° + 3x - 10° = 180°

8x + 20° = 180°

8x = 180° - 20°

8x = 160°

x = 20°

$\\$

Substituting the value of x in equation (1), we get:

$\\$

y = 5*20° + 30°

y = 100° + 30°

y = 130°

$\\$

Therefore, the answer is :

x = 20°

y = 130°

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°
