To solve the problem, we first need to understand the information given:
1. Anika constructed ray AC that bisects angle ∠A.
2. It is given that \( m \angle BAD = 46^\circ \).
When a ray bisects an angle, it means that it divides that angle into two equal parts.
In this case, ray AC bisects angle ∠A, which consists of two angles: ∠BAD and ∠DAC. Since ray AC bisects angle ∠A, it follows that:
\[
m \angle BAC = m \angle DAC
\]
Now we can find the measure of angle ∠BAC.
We know from the problem that:
- \( m \angle BAD = 46^\circ \)
Let’s represent the measures of the angles:
- \( m \angle BAC = x \)
- \( m \angle DAC = x \)
The entire angle ∠A can then be expressed as:
\[
m \angle A = m \angle BAD + m \angle DAC = 46^\circ + x
\]
Since AC bisects angle A and the measure of angle ∠A is made up of angles BAD and DAC, we have:
\[
m \angle BAD = m \angle DAC
\]
Thus, if we calculate it:
\[
m \angle A = 46^\circ + 46^\circ = 92^\circ
\]
So, the measure of angle ∠BAC is:
\[
m \angle BAC = m \angle DAC = 46^\circ
\]
Therefore, the answer is:
**The m∠BAC is 46 degrees.**
This is the correct answer because it is based on the fact that angle AC bisects angle A into two equal angles, and since one of those angles (∠BAD) is given as 46 degrees, the other angle (∠DAC or ∠BAC) is also equal to 46 degrees.
