Question

Help I don’t understand

Answer 1

x = 30

Explanation:

The 2 given angles are vertical and congruent, thus

3x - 40 = x + 20 ( subtract x from both sides )

2x - 40 = 20 ( add 40 to both sides )

2x = 60 ( divide both sides by 2 )

x = 30

Answer 2

if x is what you are looking for then, x = 30

Explanation:

3x - 40 = x + 20 (they are vertically oppositel

2x = 60

x = 30
