To find the value of \( x \), we need more information about how the angles are related. If \( x \) is one of the angles in a triangle alongside the other two angles (40° and 83°), we can use the fact that the sum of all angles in a triangle is 180°:
\[ x + 40° + 83° = 180° \]
Now, let's solve for \( x \):
- First, add 40° and 83°:
\[ 40° + 83° = 123° \]
- Now, subtract this sum from 180°:
\[ x + 123° = 180° \] \[ x = 180° - 123° \] \[ x = 57° \]
If \( x \) is indeed the third angle in a triangle with the other two angles being 40° and 83°, then \( x \) is 57°.
If this is not the correct context and there is a different relationship between the angles, please provide additional information.
