PLZZZ HELP ILL MARK BRAINLIEST TO FIRST AND CORRECT ANSWER THAT HAS WORK AND A THX TO SECOND AND CORRECT 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

i can't solve unless i know what the line is
