Question

Please help!! what is the m<4?

Answer 1

`m\angle 4 = 117\textdegree`

Explanation:

-Both
`\angle 1`and
`\angle 4` are supplementary, which they both equal to
`180\textdegree`. So, to get the measurement of
`\angle 4`, you need to subtract measure of
`\angle 1`, from
`180\textdegree` :

-Both
`\angle 1` and
`\angle 4` are supplementary:

`\angle 1 + \angle 4 = 180\textdegree`

-Find the
`m \angle 4` by subtracting the
`m \angle 1` from
`180` :

`180\textdegree - 63\textdegree = 117\textdegree`

So, the
`m\angle 4` is
`117\textdegree` .
