From the top of a bldg. 60ft high, two observers are seen on the ground. The angle of depression to the two observer are 54 degrees and 24 degrees. If the two observers and the bldg. are standing on horizontal ground and if the two observers are on the same side of the bldg. how far are the observers from each other?
I need your help how to illustrate and solve it.

What are the [H+] and [OH-] in a 0.1moldm^-3 solution of a weak acid (Ka = 1x10^-7)?
a) [H+] = 0.1, [OH-] = 1x10^-13
b) [H+] = 0.001, [OH-] = 1x10^-11
c) [H+] = 0.0001, [OH-] = 1x10^-10
d) [H+] = 1x10^-6, [OH-] = 1x10^-8
The answer is C but I want to know why.
