How do I solve this question in Geometry

75°

Step-by-step explanation:

Δ on left is 60-80-40°

Δ on right is 30-75-75°

the ∡ with the question mark has to be 75° also since it is vertical with the angle opposite it, which is also 75°

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.
