Angle 1 and angle 2 are vertical angles. If the measure of angle 1 is 87°. What is the measure of angle 2?

87 deg

Step-by-step explanation:

Theorem:

Vertical angles are congruent.

If the angles are vertical angles, they are congruent.

Congruent angles have the same measure.

If <1 measures 87deg, then <2 also measures 87 deg.

Step-by-step explanation:

Vertical angles are those opposite of each other where lines intersect. They are equal to each other. So the other angle is 87 as well.

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.

b
