What is the value of the angle marked with xxx?

Given that the sides of the quadrilateral are 3.3

The measure of one angle is 116°

We need to determine the value of x.

Value of x:

Since, the given quadrilateral is a rhombus because it has all four sides equal.

We know the property that the opposite sides of the rhombus are equal.

The measure of the opposite angle is 116°

Hence, we have;

x = measure of opposite angle

x = 116°

Then, the value of x is 116°

Therefore, the value of x is 116°
