Question

Plz help me on this question ​

Answer 1

`\boxed {129\textdegree}`

Explanation:

Both angles labeled, are actually Supplementary Angles (which two angles that add up to
`180\textdegree`). So, to find the missing measurement of an angle, which is the angle labeled in
`x`, you need to take
`51\textdegree` and subtract it from
`180\textdegree` to get the missing angle measurement:

`180\textdegree - 51\textdegree`

`\boxed {129\textdegree}` (angle measurement for the angle labeled in
`x`)
