ABCDE is a regular pentagon with centre o calculate the size of angle x

Angle x = 108 degrees

Step-by-step explanation:

Find the total angle degree of a pentagon: (n-2) x180

(5-2) x180 = 3x180 = 540

So, 540 degrees is the total degree measure.

540/5 to find the interior degree of angle x. Since it's a regular pentagon, all interior angles have the same measure.

540/5=108

Therefore, 108 degrees is the size of angle x.
