Question

Find the value of k. please help

Answer 1

Opposite angles are equal

`\\ \rm\longmapsto -k+15=k-99`

`\\ \rm\longmapsto -k-k=-99-15`

`\\ \rm\longmapsto -2k=-114`

`\\ \rm\longmapsto 2k=114`

`\\ \rm\longmapsto k=(114)/(2)`

`\\ \rm\longmapsto k=57`

Answer 2

k=57

Explanation:

-k+15=k-99(vertically opposite angles)

k=57
