Use the image to answer the question.
An illustration shows 6 angles formed by 3 intersecting lines. Two perpendicular lines form 4 right angles with each other, and the third increasing line passes through origin and the first and third quadrants. Starting from the second quadrant, the angles are labeled in a clockwise direction as 1, 2, 3, 4, 5, and 6. In the first quadrant, the increasing line divides the perpendicular angle in two parts, angle 2 and angle 3. In the third quadrant, the increasing line divides the perpendicular angle in two parts angle 5 and 6.
Angles are numbered 1–6. Which angle number is complementary and adjacent to ∠5 ?
