Lines a and b are parallel and lines e and f are parallel.
if m1 = 89°, what is m5

  m∠5 = 91°

Step-by-step explanation:

Linear angles 1 and 2 are supplementary; alternate interior angles 2 and 3 are congruent, as are corresponding angles 3 and 5. Hence angles 1 and 5 are supplementary.

  m∠5 = 180° - m∠1 = 180° -89°

  m∠5 = 91°

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 answer to this question is 3/19
