Answer:
B:45 degrees.
Step-by-step explanation:
We are given that a square ABCD .
We have to find the measure of angle BAC.
We know that each angle of square is of 90 degrees.
We know that diagonal AC bisect the angle BAD.
Therefore, measure of angle BAC=Measure of angle CAD.
Measure of angle BAD=[tex]\frac{1}{2}\times 90=45^{\circ}[/tex]
Hence, the measure of angle BAC=45 degrees.
Answer:B:45 degrees.
