Answer:
----------------------
According to the diagram we see that:
- ΔABC is a right triangle since ∠B is a right angle because all interior angles of a rectangle are right angles.
Therefore, ∠BAC and ∠BCA are complementary. We have the measure of one of the two, hence the other one is:
- m∠BAC = 90° - m∠BCA
- m∠BAC = 90° - 58°
- m∠BAC = 32°
