Parallel lines s and t are cut by a transversal r. Parallel lines s and t are cut by transversal r. Clockwise from top left, the angles formed with r and s are 1, 2, 3, 4; the angles formed with r and t are 5, 6, 7, 8. Which angles are corresponding angles? Angle3 and Angle7 Angle1 and Angle7 Angle4 and Angle6 Angle1 and Angle8

Option A.

Step-by-step explanation:

Consider the below figure attached with this question.

Corresponding angles : If a transversal line intersect two parallel lines, then it makes 4 angles at each intersection point. The angles with same relative position at each intersection is know as corresponding angles.

From the clear figure it is clear that the pair of corresponding angles are:

Therefore, the correct option is A.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

each side has a different length.
