Answer:
X = 96
Explanation:
This one is pretty simple
So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
![A+B=180](https://img.qammunity.org/2022/formulas/mathematics/high-school/z800tlbny8zx6hj63u4cxamrvgat4xyf77.png)
so we'd place in those numbers
![53+31=180](https://img.qammunity.org/2022/formulas/mathematics/high-school/wrxmq84c48rndfnkk7k3c5a7hm6j9gxeys.png)
add the two angles together
![53+31=84](https://img.qammunity.org/2022/formulas/mathematics/high-school/mcd5fza842cw4gbdoua9ny9lze4xkig5p6.png)
than we'd subtract from 180 getting the value of X
![180-84=96](https://img.qammunity.org/2022/formulas/mathematics/high-school/8tnz5wkamjwlqrsc5gpx3kh71iejgbtl14.png)
