1. Which angle is complementary to angle BAC?

Answer:
A. ACB
Step-by-step explanation:
Complementary angles are two angles whose measures add up to 90°
So BAC + ACB is 90° because ABC is 90° (the total angles of triangle is 180°)
Answer:
angle ACB
Basic facts:
complementary angles add up to 90 degrees
angles in a triangle add up to 180
Step-by-step explanation:
it is angle ACB because as we can see the triangle is a right-angle triangle
180-90=90
so we can take out angle ABC
therefore angle BAC and ACB add up to 90
