Ghlj and gstu are both parallelograms. why is ∠l ≅ ∠t?

When the opposite sides of a quadrilateral are parallel to each other then the figure is called a parallelogram. Thus,  ∠L ≅ ∠T

Given parallelograms, GHLJ and GSTU such the parallelogram GSTU is inscribed inside parallelogram GHLJ with angle G coinciding on the two parallelograms.

Recall that a property of a parallelogram states that the opposite angles of a parallelogram are equal.

Thus, angle G is similar to angle T and angle L.

Therefore, ∠L ≅ ∠T

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.
