In the figure, two lines intersect at a point. Angle 1 and angle 2 are vertical angles. Let angle 3 be an angle adjacent to angle 2, such that angle 2 and angle 3 form a linear pair. If the measure of angle 1 is $(x+50{)}^{\circ }$ and the measure of angle 3 is $(2x-20{)}^{\circ }$, what is the measure of angle 1?
