The sum of the angles in a triangle is always 180°.
Given that two angles are already known (129° and A°), we can find the value of the third angle (B°) by subtracting the sum of the known angles from 180°.
B° = 180° - (129° + A°)
Therefore, B° = 180° - (129° + A°).

To find the value of angle B, we can use the fact that the sum of all angles in a triangle is 180 degrees. The given angles are 129° and A°.
So we have the equation: 129° + A° + B° = 180°
To solve for angle B, we can rearrange the equation as follows: B° = 180° - 129° - A°
Therefore, the value of angle B is 180° - 129° - A°.
