I can help but I can’t see the diagram you mean. Could you either upload the picture or describe it (which angles are measured to the mirror or to the normal, and which angles are labelled 40°/50°)?

A reminder of the rule you’ll need: angle of incidence = angle of reflection. Draw the normal (a line perpendicular to the mirror at the point where the ray meets the mirror). Angles measured from that normal on the incident and reflected sides are equal. Also the angle between the incident and reflected rays equals twice the incidence (or reflection) angle. If you send the diagram or a clear description I’ll calculate x for you.
