In a geometric configuration, angle \( Y \) is \( 130^\circ \). Angle \( Z \), which is part of a triangle and adjacent to angle \( Y \) along a straight line, leads into a new smaller triangle containing angle \( X \). This smaller triangle has an angle \( 60^\circ \) and angle \( X \), with the third angle being a right angle. Calculate the measure of angle \( X \).
