Which set of three angles could represent the interior angles of a triangle? 26 degrees, 51 degrees, 103 degrees
29 degrees, 54 degrees, 107 degrees
35 degrees, 35 degrees, 20 degrees
10 degrees, 90 degrees, 90 degree

26 degrees, 51 degrees, 103 degrees

Step-by-step explanation:

The sum of the angles of triangles all equal exactly 180 degrees; no more or no less. Therefore, just add 26, 51, and 103 degrees to get your sum: 180 degrees.

Based on this theorem, the answer above is correct.

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.
