If ∠1 and ∠2 are vertical angles and m∠2=108°, find m∠1.

What is the inverse of the function f(x) = 2x + 1?

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

Ihonestly have no clue if it's each or none.
