Here is the question-

The following diagonal is drawn in a regular decagon, creating an octagon and a quadrilateral. What is the measure of x?

This is the image above ^

All I know so far is that the angle sum is 1440\(^\circ\)

Can someone show me how to compleate this problem?

thanks in advance

I worked this out before!  The answer is 30 degrees.

Thank you in advance
