Without diagram or more info, we don't know which angle is A or what X indicates.
To find the value of angle A in triangle ABC, we need to use the property of a bisector.
Let's assume that AD bisects angle A in triangle ABC. This means that angle BAD is congruent to angle DAC.
Now, let's analyze the answer choices:
1. If the value of angle A is 60 degrees, then angle BAD would be 30 degrees and angle DAC would also be 30 degrees. However, in a right triangle, the sum of the two acute angles is always 90 degrees. So, this is not possible.
2. If the value of angle A is 90 degrees, then angle BAD would be 45 degrees and angle DAC would also be 45 degrees. This is a valid scenario because the sum of the two acute angles in a right triangle is 90 degrees. So, this could be a possible answer.
3. If the value of angle A is 100 degrees, then angle BAD would be 50 degrees and angle DAC would also be 50 degrees. Again, this is not possible as the sum of the two acute angles in a right triangle is always 90 degrees.
4. If the value of angle A is 120 degrees, then angle BAD would be 60 degrees and angle DAC would also be 60 degrees. Once again, this is not possible as the sum of the two acute angles in a right triangle is 90 degrees.
Based on our analysis, we can conclude that the value of angle A in triangle ABC, if AD bisects it, is 90 degrees. Therefore, the correct answer is option 2.
