A horizontal line and a line slanting slightly upwards from left to right are intersected by a nearly vertical line. The supplementary angles formed above the point of intersection with the nearly vertical line and the horizontal line are an unlabeled angle and an angle labeled A. Angle A is on the right and is slightly greater than 90 degrees. The supplementary angles formed above the point of intersection with the nearly vertical line and the other line running left to right are an unlabeled angle and an angle labeled B. Angle B is on the left and is slightly less than 90 degrees.
Are the angles supplementary if m∠A=98°
and m∠B=88°
?

To determine if angles A and B are supplementary, we need to check if their measures add up to 180 degrees.
Given:
Now, we can add the two angles together: m∠A + m∠B = 98° + 88° = 186°
Since 186° is greater than 180°, angles A and B are not supplementary.
Therefore, the correct response is: No, they do not add up to 180°.
