In ABCD, the measure of D=90°, BD = 20, CB = 29, and DC = 21. What is the value of the cosine of ZC to the nearest hundredth?

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.

the solution is 12x-6y

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
