Question

So confused! Anyone good at this?

Answer 1

x = 90 degrees.

Explanation:

These are all regular octagons and the value of x = 2 * external angle of an octagon.

The sum of external angles of a polygon sum to 360 degrees and in the case of an octagon each external angle = 360/8 = 45 dgrees,

So angle x = 2*45 = 90 degrees.
