Answer:

x is 72 degrees

Step-by-step explanation:

To find the measure of x, you need to know the sum of the interior angles of the pentagon.

Sum = (n - 2) x 180

Sum = (5 - 2) x 180

Sum = 3 x 180

Sum = 540

Now divide this by 5, the number of sides

540/5 = 108 degrees for each angle of the pentagon.

To find the measure of x, look at the opposite angle, which is 108 degrees

180 - 108 = 72

The measure of angle x is 72 degrees.
