Answer:

x = 6

Explanation:

The 2 angles are vertically opposite and are congruent, so

5x + 100 = 3x + 112 ( subtract 3x from both sides )

2x + 100 = 112 ( subtract 100 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Answer:

vertically opposite angles are equal

3x+112°=5x+100°

112°-100°=5x-3x

12°=2x

12°÷2=2x÷2

6°=x

therefore x=6°

Explanation:

hope this is helpful
