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.
