Question

# _______________.

Hint:

### Polygon is a two- dimensional closed figure which is consist of three or more-line segments. Each polygon has different properties. One of the polygons is quadrilateral. Quadrilateral is a four-sided polygon with four angles and the sum of all angles of a quadrilateral is . Here, we have to find the measure of in the given quadrilateral using the properties of the quadrilateral.

## The correct answer is:

### In the question there is a figure with some measurements of angles in it using which we have to find the value of y.

We know that, the consecutive angles of a parallelogram are supplementary.

So, the value of y is .

Therefore, the correct option is d, i.e., .

Parallelogram is a four-sided polygon whose opposite sides are parallel and equal to each other and the opposite angles are equal to each other. The sum of all angles of a parallelogram is and sum of two consecutive angles is . The diagonals of a parallelogram bisect each other and the angle into two equal halves. Here, we have to use these properties of a parallelogram and solve the given question.
