What is the value of x?
Three intersecting lines. Two of the lines are perpendicular and the other is diagonal. Along the top side of the diagonal line, the angles are labeled Y degrees, right angle, and 3X plus 7 degrees. Along the bottom side of the diagonal line, one angle is labeled 5Y plus 10 degrees, and the other angle is not labeled, but is vertical to the angle labeled 3X plus 7 degrees.
