Question

Answer the question below.

Answer 1

• 32°

----------------------

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°
