Answer:

C

Step-by-step explanation:

Since AB and CD are perpendicular to each other, then

∠ 1 + ∠ 2 = 90°, that is

3x + 3 + 30 = 90

3x + 33 = 90 ( subtract 33 from both sides )

3x = 57 ( divide both sides by 3 )

x = 19 → C

Answer:

C

Step-by-step explanation:

Lines AB and CD are perpendicular to each other.So,

∠1 + ∠2 = 90

3x + 3 + 30 = 90

3x +33 = 90

3x = 90 -33

3x =57

x = 57/3

x= 19
