Proof: x=14
statement....................................reason
m ∠ 1=%282x-3%29°
m+∠ 3=25°.....................given
m ∠ 1 and m ∠ 3 are vertical angles...................property of vertical angles
m ∠ 1 = m ∠ 3 .....................................vertical angles are congruent
2x-3=25...............substitution property
2x=28..................addition property
x=14........................division property
