Final answer:
The question appears to have multiple parts with insufficient detail for a full answer. It includes discussing intersecting lines in geometry and observations in astronomy, as well as separate chemistry concepts like dissociation constants and molar concentrations.
Step-by-step explanation:
The original question seems to be describing two different scenarios involving angles, one of which pertains to intersecting lines and another to astronomical observations, while the other excerpts relate to chemistry.
In the first scenario, we're given that lines HI and JK intersect at point O and that the measure of angle KOH is 110 degrees. To find the measure of angle x, one would typically need additional information about the intersecting lines and their angles. Without this information, it's impossible to provide a direct answer.
In the astronomical scenario, the problem seems to describe a method for measuring the width of the Moon based on similar triangles. The calculations involve the use of proportions to determine the distances and sizes of celestial objects.
The chemistry excerpts discuss concepts such as dissociation constants, the pOH and pH calculations, and molar concentrations in solution. This suggests that the question may be multi-disciplinary or that there has been an error in compiling the question's information.
