Sagot :
Answer:
Angle 1 and Angle 5
Step-by-step explanation:
If angles are complementary, they add up to 90 degrees...
Angles 1, 5, and 6 add up to 180 degrees, as they are on a line. We know that Angle 6 is a right angle, meaning it is 90 degrees, which means...
Angle 1 + Angle 5 + 90 = 180
Subtract 90 from both sides
Angle 1 + Angle 5 = 90
Therefore they are complementary
Why the others are wrong
Angle 3 and Angle 5 : Angle 3 is already 90 degrees, so it cannot have a complement
Angle 3 and Angle 1 : Angle 3 is already 90 degrees, so it cannot have a complement (same as above)
Angle 4 and Angle 6: Angle 6 is already 90 degrees, so it cannot have a complement
