Answer:
The amendment becomes part of the constitution.
Explanation:
After congress has approved a proposed amendment to the constitution, then the amendment becomes part of the constitution: an amendment becomes part of the constitution after it is proposed by two-thirds of the House of Representatives and Senate, and ratified by three-quarters of the States (which is 38 of the 50 States in USA).
