Answer:

x = 32

Explanation:

The 2 given angles are vertically opposite and congruent, so

2x - 20 = 44 ( add 20 to both sides )

2x = 64 ( divide both sides by 2 )

x = 32

Answer:

Explanation:

2x-20 = 44, because vertical angles are congruent

2x = 44+20, combine like terms

2x = 64, divide both sides by 2

x= 32
