Answer 1

k = 60

Explanation:

Because supplementary angles are either 2 angles where the sum equals 180, if we take 60 for
`\angle {1}`, and then add it to
`\angle {2}`, we get 2(60) = 120 for
`\angle 2` and 60 for
`\angle 1`, meaning that if we add the values of both angles together, it will be 120 + 60 = 180.

Answer 2

k=60

Explanation:

k+2k=180

3k=180

k=60
