Answer:

40

Explanation:

Assuming that these two lines are parallel, the two angle measures must be supplementary, or add to 180. Thus:

2k+(2k+20)=180

4k+20=180

4k=160

k=40

Answer:

40

Explanation:

2k and 2k + 20 are co - interior angles.

Sum of co - interior angles is 180,

2k + 2k + 20 = 180

4k = 180 - 20

4k = 160

k = 160 / 4

x = 40
