Question

Find the value of n. olease help

Answer 1

`\\ \rm\longmapsto -3n-13=n-369`

`\\ \rm\longmapsto -3n-n=-369+13`

`\\ \rm\longmapsto -4n=-356`

`\\ \rm\longmapsto 4n=356`

`\\ \rm\longmapsto n=(356)/(4)`

`\\ \rm\longmapsto n=89`

Answer 2

Explanation:

(-3n-13)+(n-369)=360degrees

-3n-13+n-369=360degrees

-3n+n-369-13=360degrees

-2n-382=360 degrees

-2n=(360+382)degrees

-2n=742

n=742 divided by - 2

= - 371
