The video tutorial explains how to find the value of X in a geometric problem involving a circle with tangents. It presents two methods: the first uses arc and angle calculations, while the second employs quadrilateral properties and angle sums. Both methods lead to the same result, demonstrating the value of X as 5 degrees. The video concludes with a call to action for viewers to subscribe.
